The main aim of this research is to increase the strength properties of the weak soil by using stabilizing materials for the construction of high raised buildings on weak soils. As we all know that the most important thing in construction industry is soil. In this research we are adding stabilizing materials like lime and glass fibers to the weak soil to increase the strength parameters of the soil. The addition of stabilizing materials and admixtures to the soil leads to the increase in the strength parameters of the soil. There are various Infrastructural projects which are constructed on the soil, in many of these cases the black cotton soil is not suitable, because the Black cotton soil is weak in strength and which has low engineering properties. Black cotton soil has more swelling property and high shrinkage nature. To overcome these problems and to improve the engineering properties of the black cotton soil, we are adding Lime and Glass fibers as the stabilizing materials in the weak black cotton soil. The engineering properties like strength, compressibility and bearing capacity of the soil were increased by stabilizing the weak soil these stabilizing materials. This work mainly concentrates on the feasibility of the usage of lime and glass fibers as the stabilizing materials for the black cotton soil. The percentage of Lime and glass Fibers used in black cotton soil varies in different proportions like 2%, 4%, 6%, 8% and 10%. All the necessary tests were conducted to get the results. The properties like Liquid limit, Plastic limit, Compaction characteristics values and Differential free swell index of soil have been studied in this research.

In this study coarse aggregates and cement are partially replaced in the concrete with similar materials like coconut shells and glass powder. While production of the cement there is a lot of pollution to the environment and which causes health issues to the society. In the same way while production of the course aggregates which releases lot of dust into the atmosphere which causes damage to human lives. We can obtain some advantages by partially replacing the coarse aggregates and cement in the concrete. As we all know that the Cement and the coarse aggregates are the main ingredients in the concrete. The cost of these materials is getting increased day by day. There are some of the materials proposed by many researchers to lesser the cost of the concrete and to improve the strength characteristics of the concrete. For coarse aggregates, the coconut shell is the most preferable and it has more potential to the partial replacement of the coarse aggregates in concrete. As well as there is a similar material which used to partially replacement of the cement is waste glass powder. As we observe at many places there is a lot of wastage of glass will produce throughout the year. Mainly glass is the composition of silica. When the glass is crushed into very small size as powder it experienced to the pozzolanic reactions with hydrates in the cement, and calcium silicate hydrate will be formed. The main aim of this research is utilization of the waste material in the concrete as well as decreasing the cost of the construction by using these waste materials in the concrete, by performing all these things we can easily reduce the pollution of the environment and clean the environment by using these waste materials in the concrete..

This research concentrates on the evaluation of mechanical properties of high strength concrete using fibers and admixtures. Now-a-days High strength concrete is used in the construction to get the more strength and durability. High strength concrete mix of M40 grade is designed by adding fibers and admixtures. Admixtures like Super plasticizer & master glenim are used to replace the cement content in the mix. Chemical admixtures are used to decrease the water content in the concrete such that its workability and compressive strength increased. Along with that as the concrete is weak in tension, to overcome that, fibers of polypropylene were used. Fibers can increase the tensile behaviour of the concrete beam. The specimens were prepared by adding the fibers and mineral admixtures to the high strength (M40) concrete and conventional concrete and tested for compressive strength, Slump cone test, Modulus of elasticity and flexural strength at 7,14, 28 & 56 days. Based on the experimental values, it is clearly identified that all the results were obtained target mean strength. Experimental data shows that using fiber content from 0.5% to 1% can increase all mechanical properties of the concrete but using more than above mentioned content will leads to decrement of strength parameters of the concrete.

This paper mainly concentrates on the uses and applications of EPS geo-foams and geo-membranes in construction industry like Bridges and Embankments over weak soil (compressible soils). If any external load is acting on weak soil, it will undergo settlement and the soil will be compressed. To overcome these settlements and compression of the weak soils, in this research we suggest EPS geo-foams. The EPS means “Expanded Poly Styrene”, it is a light weight material which is 1% weight of soil and it is less than 10% weight of other light weight materials and it is available in different densities. It has high compressive resistance and it reduces settlement of weak soil. It is generally used as a soil fill replacement material. If the soil contains any moisture content, the geo membrane acts like a water barrier for the geo-foam material. Geo-membrane is a thin continues polymeric sheets and it is a geo synthetic material, it is generally used in construction industry and geotechnical applications. If we place different types of densities of EPS geo-foam blocks and geo-membranes over weak soil in bridges and embankments, the soil behaviour is changing and attaining stability. Finally based upon the behaviour of weak soil we conclude that, at which density of the EPS blocks the soil attain more strength and how other strength parameters has been related to density by conducting the different tests.
