Professor, Dept. of civil engineering, L.D.R.P institute of technology & Research ---------------------------------------------------------------------***--------------------------------------------------------------------Aggregate Abstract - Infrastructure Development across the world has created the demand for construction materials. Concrete is the premier in civil engineering construction material. Concrete manufacturing includes the consumption of ingredients Such as cement, Sand, aggregates, water and admixtures. Among all these ingredients aggregates form the major part. In the other hand, we use alternative waste materials in place of natural aggregates in concrete production which can make concrete as environment friendly material. Examples of such materials are Coconut shells, Scrap tires, plastic waste, Recycled aggregates etc. If these materials are used in construction industry, the pollution and disposal problems may be partly reduced.
The fine aggregate which is round in shape is used in the experiment with siliceous sand. Rubber tyre chips A rubber tyre chips of size 20mm are used with specific gravity of 1.16 Water A portable water of Ph 7 to 8 is used Experimental Setup
1. INTRODUCTION
In this experiment consist of 4 types of mix proportions replaced by coarse aggregate in 0, 10, 20, 30% of waste rubber tyre in M20 grade of concrete.
Concrete is basically made of aggregates, cementitious materials paste, which includes cementitious materials and water. Major problems to the local authority to identify the potential and recycling of waste products like Waste rubber tires which are expensive and decreases the number of landfills. The disposals of waste tires to landfill are legally banned in all the countries. The main purpose of study on waste rubber tyre in concrete for eco-friendly environment. Decomposition of waste rubber tire which contains composed materials and it causes serious contamination for environment condition. Another process of decomposing is burning that can cause pollution in environment and the gases exhausted are harmful.
Total number of 48 cubes (150×150×150mm) were casted for durability test and compressive strength. Compressive test was performed at the age of 14 and 28 days and the durability test at the age of 28 days of curing. Compressive strength of concrete is calculated using compressive strength machine
2.Methodology In this method, our present study aims the use of waste rubber tire as a partial replacement of coarse aggregate to produce concrete in M20 grade of mix. Different partial replacement of rubber chips (0, 10, 20, & 30%) by the volume of coarse aggregate casted and tested for compressive strength in water on 14 and 28 days. Materials and Methods Materials Cement Portland cement with OPC grade 53 cement is used.
