Abstract:

In the present scenario, several buildings are being constructed ranging from ordinary residential buildings to sky-scrap structures. Invariably in all the structures, concrete plays a vital role in construction. Generally concrete is a mixture of cement, fine aggregate (River sand), coarse aggregate, water and type of admixtures used depends upon the situations. Now-adays good sand is extracted and transported from river bed being in a long distance. The extraction of sand has become a serious issue, posing environmental degradation, thereby causing serious threats of flood or diversion of water flow. Never the less the resources are also exhausting very rapidly and economical. To overcome from this crisis, partial replacement of cement with GGBS and fine aggregate with eps beads can be an economic alternative. This project focuses on investigating the characteristics of M25 grade of concrete with cement partially replace with GGBS 25%, 35% and fine aggregate replace with eps beads of 0.4%,0.6%, 0.8% respectively. The compressive strength of concrete is increases from 28.4 N/mm2 to 35.6 N/mm2 at 25% of fly ash and 0.6% of eps beads replacement; increases from 28.4 N/mm2 to 34.1 N/mm2 at 35% of fly ash and 0.6% of eps beads replacement.
