Assessment of Mix Design for Government Project

Abstract

In this paper a study on mix design of Indian standard method IS 10262-2019, IS 456:2000 has been made for M20, M25 grades and the comparison of water-cement ratio water content, cement content, fine aggregate and coarse aggregate content has been observed and done and been presented. It was concluded that new revised version of Indian Standard code has the lowest value of water/cement ratio and highest quantity of cement as compared to other standards. Concrete mix-design is the method to transform the required engineering properties into the composition of the concrete mixture in terms of kg/m³ of cement, water, sand and coarse aggregate. There are two types of mix-design depending on the complexity of the required performances: simple or complex mix design. Complex mix design also includes the calculation of the slump loss depending on the time and temperature transportation, as well as the presence of chemical admixtures. The reason of enormous use of concrete from many years is its universal versatility, economy, ease in mould to any shape and good durability. Also, ingredients of concrete are easily available in any part of the country.
