It is low-cost and environmental-friendly material very useful even in rural housing industry. FaL-G in certain proportions, as a building material is an outcome of innovation to promote large-scale utilization of fly ash. It gains strength like any other hydraulic cement in the presence of water and it is water resistant when hardened. This paper addresses the technology of making FaL-G mortar compressed hollow blocks with lowcalcium (Class F) dry fly ash as the base material. The FaL-G masonry hollow blocks were prepared without the use of conventional cement. Quarry dust and sand were used as fine aggregates as sustainable materials. The properties and compressive strength of FaL-G masonry hollow blocks were tested with different parameters. The experimental results reveal that the FaL-G hollow blocks are suitable to be used for the construction of masonry structures. Keywords: compressive strength. fly ash, gypsum, lime, mortar, quarry dust, sand Effect of Landuse/ Land covers onRunoffinVrishabhavathi Basin –a Case Study CB Jagadeesh, HS ShivakumarNaiklal, NS Sitaram Urban growth is a global phenomenon that comes with human settlements and accompanying anthropogenic activities plays an important role in the land use and land cover change. The city of Bangalore grew to 716 Km2 in 2007 with the creation of Bruhat Bangalore MahanagaraPalike (Pavan Srinath, 2014). The rapid urbanization in last four decades resulting in increase of paved area and decrease in agricultural land area which used to act as a percolation zone. It has also brought reduction in arable land, forest land and water bodies. The change of Land cover and land use in major cities is one of the major reasons for climate change. The paper is focused on change in Land cover and Land use that have taken place in Vrishabavathisubwatershed (Upstream of Gali Anjaneya Temple of Bangalore) from 1973 to 2014 by using remote sensing and GIS techniques. The conclusions are drawn based on analyzing the multi-temporal and multi-spectral Landsat satellite images.

With this perspective, an experimental study is carried out to assess the possibility of using brick masonry waste as a partial replacement for natural coarse aggregate (NCA) in concrete mixes. Brick bats or brick masonry waste are crushed using hammer to recover coarse recycled brick aggregate (CRBA). M40 grade concrete mix is designed as per IS 10262:2009, by considering the properties of natural aggregates. NCA is partially replaced by CRBA at 10%, 20%, 30% and 40% in concrete mixes. Totally five concrete mixes (including control mix made of NCA and NFA) are considered in the study. The workability of the concrete mixes decreases with an increase in CRBA content. A marginal reduction in 28 days compressive strength is observed up to 20% replacement of NCA by CRBA. At 30% and 40% replacement level, the reduction in compressive strength is about 15% and 30% respectively. The tensile strength decreases with increase in CRBA content in concrete mix.

Since the development of plastic earlier this century, it has become a popular material used in different ways. They are cheap, durable and easy to make. In today’s world, plastic is used to make or wrap many items, we buy or use. But the main problem arises when we no longer want those items and we have to discard them. As the production cost of plastic is very less, it is readily available in the market. The cheapness means plastic gets discarded easily, its long life means it doesn’t decompose easily and requires high ultraviolet ray to break down. In the 21st century, one of the major environmental issues is arising due to the plastic waste. Plastic is non-biodegradable hence the discarded plastics are affecting our environment gravely. Due to the huge popularity of plastic as a production material, decrease in plastic usage policies isn’t encouraged by manufacturing companies, rather it is estimated that the plastic usage rate going to be double for the next 10 Department of Civil Engineering ƒ‰‡͵͵ 213

Firstly, manufacturing of PC is emitting 5% of the global CO2 into the atmosphere causing global warming. Secondly, manufacture of PC requires limestone and clay that are depleting day by day. To produce 1 ton of PC, 1.6 tons of raw materials are needed to be extracted from the earth. To overcome the above problem a new concrete called Geopolymer is used. Geopolymer is an amorphous alumino-silicate product that exhibits the ideal hardening properties of elements. In the present study the strength development of geo polymer concrete is determined by varying temperature. To prepare geopolymer concrete the material used is Ground Granulated Blast Furnace Slag, sodium hydroxide activator and hydrated sodium silicate binder. The sodium hydroxide is varied in two molarities, 8 and 10 respectively. The sodium silicate had 30% water content in it. The curing was done in the oven with varying temperatures of 60, 80 and 100 degrees. The compressive strength test, split tensile test and flexural strength test showed higher strength at 8 molars and curing temperature being 100 degrees.

The author of the present study is of the opinion, that, such practices of brick waste utilization are really not sustainable, as, this inert waste can be utilized, to produce durable and attractive (in terms of color and texture) building units. With this premise, this experimental study is pursued to assess the potential of brick masonry waste for making Cement Stabilized Masonry Blocks (CSMB). The Brick Powder (BP) is obtained by crushing the brick masonry waste obtained from dump yards and used in conjunction with Natural Fine Aggregate (NFA). Fifteen mix compositions are considered by varying BP, NFA as 60:40, 70:30 and 80:20 respectively, with the percentage of cement content as 5, 8, 10, 12 and 15. Wet and dry compressive strength of each of the mix variants is determined by performing tests on cube specimens of size 70. 6mm.The wet compressive strength is found to be 0.75 times the dry compressive strength. A minimum of 10% of cement content is required to achieve the strength in excess of 3.5 Mpa. Keywords: Cement Stabilized Masonry Blocks (CSMB), Brick Powder (BP), Natural Fine Aggregate (NFA). Strength and Water Absorption Characteristics of Cement Stabilized Masonry Blocks Using Brick Masonry Waste B. M. Vinay Kumar B. V. Surendra Abstract The experimental study deals with assessment of strength and water absorption of cement stabilized masonry blocks (CSMB) using brick masonry waste as prime ingredient. The brick powder (BP) is recovered from brick masonry waste, and it is used in conjunction with natural fine aggregate (NFA) in production of CSMB units. The size of CSMB specimens corresponds to 190 × 90 × 90 mm as per IS 1725:2013 and prepared by applying compaction pressure of 3.0 MPa. Nine mix compositions are considered by varying BP, NFA as 60:40, 70:30 and 80:20, respectively, with percentage of cement content as 8, 10, and 12. The wet compressive strength of CSMB specimens is determined at end of 28 days, and the test results are statisticallyanalyzed. The average compressive strength of CSMB specimens in wet condition meets the compliance requirement of 3.5 MPa for the different values of prime variants included in the study. The water absorption characteristics are also in compliance with the requirement of being less than 18% in all the cases.

The concrete mix is designed for target strength of 60 MPa. Four mixes are considered in the study viz., Control Mix (CM) with natural aggregates, 20% replacement of CRCA, FRCA and both. The fresh and hardened properties are assessed for all the four mixes. The experimental results indicate the satisfactory performance of all the four mixes with respect to hardened properties. The HPC mixes with 20% FRCA content shows reduction in workability and requires a higher dosage of Superplasticizer (SP) to achieve a slump of 170 ± 10 mm. The durability tests such as sulphate and acid attack are conducted for the mix containing 20% CRCA and FRCA. The mix is found to be least susceptible to sulphate attack. The significant reduction in compressive strength is noticed, when the HPC mix is exposed to H2SO4 solution.

Use of Geosynthetics for Sustainable Pavements G. R. Harish K. Madesh N. Swathi G. R. Vijayabhaskara Reddy H. Deepak Abstract Nowadays, the pavements are subjected to premature failure due to rapid growth in vehicular traffic. Among various modes of failure, rutting and fatigue are the predominant ones. In addition to this, there is scarcity for good quality materials. To address these problems, the engineers are forced to design new/alternate construction materials. Geosynthetic is one among those new materials. In this study, model pavement sections were built in the field under unreinforced and geosynthetic reinforced conditions. For reinforcement, uniaxial geogrid, geotextile, biaxial geogrid and geocell were considered. The reinforcement was provided at the interface of subgrade and granular sub-base course layers. The loading was done by passing a two wheeler over the pavement at an average speed of 20 kmph. Each model pavement section was subjected to 100 vehicular passes. During testing, the rut depth was measured at various locations along the length and width of the pavement at the end of 10 vehicular passes. The Department of Civil Engineering ƒ‰‡Ͷ͹ 227

Among various forms of geosynthetics, biaxial geogrids and geocell were found to be suitable for pavement application. With the provision of biaxial geogrid and geocell, the rut depth was found to be reduced by 28% and 56%, respectively. In addition, the provision of geosynthetics reduced the surface heaving with geocell being very effective and reduced surface heave results in improved riding quality of the pavements leading to sustainable pavements.

Hence the concrete technologists must search for some economical alternative to the coarse aggregate. Coarse aggregate is replaced with coconut shell in concrete. Constant water to cement ratio of 0.45 was maintained for all the concretes. In this study, M 30 grade of concrete was produced by replacing coarse aggregate by coconut shell. Concrete produced by 0%, 10%, 20%, 30% replacement of coarse aggregate by coconut shell. Twenty four cubes were casted and their compressive strength was evaluated at 7 and 28 days. Twelve cylinders and twelve beams were casted and their split tensile strength and flexural strength were evaluated at 28 days. The compressive strength of concrete reduced as the percentage replacement increased. These results showed that Coconut shell in concrete can be used in lightweight concrete construction. Its utilization is cost effective and eco friendly. Keywords — coarse aggregate, coconut shell, compressive strength, flexural strength, partial replacement, tensile strength.

It is able to flow under its own weight, completely filling formwork and achieving full compaction, even in the presence of congested reinforcement. The hardened concrete is dense, homogeneous and has the same engineering properties and durability as traditional vibrated concrete. The inclusion of fiber reinforcement in concrete, mortar and cement paste can enhance many of the engineering properties of the basic materials, such as fracture toughness, flexural strength and resistance to fatigue, impact, thermal shock and spalling. In recent years, a great deal of interest has been created worldwide on the potential applications of natural fiber reinforced, cement based composites. Investigations have been carried out in many countries on various mechanical properties, physical performance and durability of cement based matrices reinforced with steel fibers. These fibers help to transfer loads at the internal micro cracks. The behavior of SCC as a structural material can be improved if adequate polypropelene fiber reinforcement is added to SCC mix composition. The fiber reinforcement mechanisms can convert the brittle behavior of the cement based material into a pseudo-ductile behavior up to a crack width that is acceptable under the structural design.

Pile foundations are meant to transfer the enormous load to the deeper depth. Straight shafted file are widely used in cohesion less soil conditions than in expensive soils. Now days these piles are designed not only to transfer the load, as a group they act as settlement reducers. These piles may be cast in situ or precast, and are required as the primary foundation support for a wide range of buildings, towers, dams and other massive structures. Analysis of pile-soil interaction is more complicated, practical testing to analyse the strength and settlement of each pile is cumbersome. The pile capacity is often difficult to assess even by means of a static loading test. The oldest approach is simply to state that the ultimate load in a test is equal to the applied load when the movement of the pile head is 10 percent of the pile toe diameter, so a proper and reliable analytical method was in urgent need to be developed. In this study analysis of straight shafted pile for has been carried out under cohesion less soil conditions (sand) by varying the length and diameter, to determine the ultimate strength and maximum displacement.

An Experimental Analysis of Flexural Behaviour of the Bubble Deck Slab in Comparison with Conventional Concrete Slab Yogesh K S1 Channabasava2 1, 2Assistant Professor 1,2Department of Civil Engineering 1, 2New Horizon College of Engineering, Bengaluru, Karanataka, India Abstract— Reinforced concrete slabs are one of the most common components in modern building construction. Efforts are being continued from past decades to reduce the dead weight and to improve the performance of the slab. Bubble deck slab system are a new and innovative type of structural concrete slab system developed to allow for lighter self-weight of the structure while maintaining similar load carrying capacity of a solid slab. In these slabs shear and punching shear resistance of the BubbleDeck floor is significantly less than a solid deck since resistance is directly related to the depth of concrete. In this work efforts are made to understand the load deflection behaviour of bubble deck in compersion with the conventional slab system. Quantity estimation results showned that there was a considerable reduction in the weight of concrete in case of bubble deck slab. A scaled down models are tested under nine point loading system to determine the load and deflection behaviour of both the slabs. Test results have proven that the bubble deck slab system is more efficient in carrrying more load and undergo more deflection compared to conventional rcc slab system.

Thus column with greater stiffness than beam is provided. The present work deals with three dimensional nonlinear finite element (FE) analyses of a reinforced concrete column subjected to blast loading. The finite element package ABAQUS/Explicit was used to model a reinforced concrete column and the concrete damage plasticity approach was used to define the non-linearity of concrete. The stress-strain response of concrete and reinforcement has been simulated using concrete damaged plasticity model and elastic-perfectly plastic model, respectively. TNT explosive has been simulated using Air blast interaction under CONWEP definition. Parametric sensitivity studies have been performed by varying the spacing between stirrups as 125, 175, 225 and 275 mm and also diameter of main reinforcement bars are varied as 16, a20, 25, 28 and 32 mm to determine the displacement and stress variations. Efforts are also made to determine the effects of incident blast wave falling on the different face of the column. It is observed from the results that modeled column structure undergo significant deformation with variations. It is also observed that blast resistance increases as the spacing between stirrups decreases. Also, deformation of the column decreases as the diameter of the reinforcement bars increases.

Efforts are being continued from past decades to reduce the dead weight and to improve the performance of the slab. Bubble deck slab system are a new and innovative type of structural concrete slab system developed to allow for lighter self-weight of the structure while maintaining similar load carrying capacity of a solid slab. In these slabs shear and punching shear resistance of the BubbleDeck floor is significantly less than a solid deck since resistance is directly related to the depth of concrete. In this work efforts are made to understand the load deflection behaviour of bubble deck in compersion with the conventional slab system. Quantity estimation results showned that there was a considerable reduction in the weight of concrete in case of bubble deck slab. A scaled down models are tested under nine point loading system to determine the load and deflection behaviour of both the slabs. Test results have proven that the bubble deck slab system is more efficient in carrrying more load and undergo more deflection compared to conventional rcc slab system.

Keywords: Marble Dust, Compressive Strength, Split Tensile Strength HYDROLOGIC ANALYSIS ON INSTANTANEOUS UINT HYDROGRAPH USING CLARK’S METHOD S. SatyaPriya Senior Assistant Professor, Department of Civil Engineering, New Horizon college of Engineering, Bangalore, India Abstract: The scope of the study to develop a method to estimate Time of Concentration (T c) and Storage Coefficient (R) to develop Clark’s Instantaneous Unit Hydrograph (CIUH). T c is estimated from Time Area Diagram of the catchment and R is determined using optimization approach based on Downhill Simplex technique (code written in FORTRAN). Four different objective functions are used in optimization to determine R. The sum of least squares objective function is used in a novel way by relating it to slope of a linear regression best fit line drawn between observed and simulated peak discharge values to find R. Physical parameters (delineation, land slope, stream lengths and associated drainage areas) of the catchment are derived from SPOT satellite imageries of the basin using ERDAS: Arc GIS is used for geographic data processing. Ten randomly selected rainfall–runoff events are used for calibration and five for validation. Using CIUH, a Direct surface runoff hydrograph (DSRH) is developed. Kaha catchment (5,598 km2), part of Indus river system, located in semi-arid region of Pakistan and dominated by hill torrent flows is used to demonstrate the applicability of proposed approach. Model results during validation are very good with model efficiency of more than 95% and root mean square error of less than 6%. Impact of variation in model parameters T c and R on DSRH is investigated. It is identified that DSRH is more sensitive to R compared to T c. Relatively equal values of R and T c reveal that shape of DSRH for a large catchment depends on both runoff diffusion and translation flow effects. The runoff diffusion effect is found to be dominant. Keywords: Time of Concentration, Storage Coefficient, ERDAS, Arc GIS, DSRH Department of Civil Engineering ƒ‰‡͸͵ 243
