A Review Paper on Evaluation and Performance of Concrete by Partial Replacement of Fine Aggregate by Stone Dust and Coarse Aggregate by Construction Waste for Rigid Pavement in Rural Areas

摘要

India produce a large amount of waste materials from different sectors like industrial, construction, agriculture etc. which are just dumped on the land. This may lead to large areas of land which becomes difficult to find. And also now a day’s fine aggregate(sand) is very expensive. So, that by adding alternative materials as partial replacement in fine aggregate & coarse aggregate would give better saving and environmental free. Therefore, it is enhanced alternative material to use in a rigid payment construction in civil engineering and also cost of construction may also reduce to the cost of conventional concrete. In this project I have added two types of alternative material named as stone dust and construction waste in concrete mix with a percentage variation of 10%,20%,30%,40%, &50% for fine aggregate and 5%,10%,15%,20%, &25% for coarse aggregate. In the present investigation our experiment will be carried out to study the compressive strength of concrete in standard mould cube cast is to ready in 7 & 28 days curing. M30 grade of concrete is designed using PPC for this experiment. Compressive strength will be determined at different replacement level of fine aggregate & coarse aggregate with respect to conventional concrete and optimum replacement level will be determined based on compressive strength.
