Get PriceThe aggregates are of two kinds, coarse aggregate such as crushed limestone or granite and fine aggregate such as river sand or manufactured sand. Various chemical admixtures can also be added to achieve varied properties. Water is mixed in concrete so that the concrete gets its shape and then gets hardened through a process called hydration.
Get Pricereplacement of CSFB aggregate concrete is marginally higher than that of the river sand aggregate concrete at age of 7 days, 14 days and 28 days respectively. Tiara Darshita et al. (June 2014),studied about the strength and workability of different grades of concrete by partial replacement of fine aggregate by crushed brick and recycled glass
Get Priceproved that ceramic aggregate and crushed sand can also partial replacement for course aggregate and fine aggregate in concrete. Based on the experimental results it is evident that the optimum percentage of ceramic aggregate is 20% and crushed sand is 60% partial replacement in concrete
Get Price1 Replacement fine aggregate by crushed limestone reduces workability of concrete mixes especially in leaner mixes (poor). 2 Concrete mixes with crushed limestone fine aggregate needs more water to maintain the same workability than that of natural sand. The amounts of needed water are rather not high ranging about (5-10)% of cement quantity.
