Alccofine, Crumb rubber, Cement, Coarse Aggregate, Water
This project represents the effects of using alccofine material in high strength concrete of M45 grade and rubber crumbed material for making that light weight concrete of this cube specimen. We are partially replacing some Portland cement in design mix-1, alccofine 20% by weight of binder (cement). Alccofine replace varies from 15 to 25 % .These types of concrete contain alccofine materials with different proportion in addition to ordinary Portland cement concrete were investigation and tests for compressive strength for ages 7days and 28days. The 3 cubes of 150 x 150 x 150mm were test for compressive strength and reported on average of these results. The 3 cylinders having diameter of 150 mm and height of 300 mm tested on 7 days and 28 days and flexural strength and reported on average of these results. After that we have replace the fine and coarse aggregate with different types of crumb rubber respectively. The main aim of replacing the aggregate to crumb rubber is to make the concrete considerably light in weight. We replace fine and coarse aggregate respectively with crumb rubber in proportion 5 to 15%. We casted a cube and measured their compressive strength. After that we combine the both material with their optimum percentage and 0made a cube of their combination and measured its compressive strength.
