Study of Recycled Aggregate in Concrete By Using Mineral Admixture (GGBS) & Manufsctured Sand

Abstract

Reuse of concrete waste concrete grade M:30 use of manufactured sand in replacement of natural sand in concrete, GGBS, ground granulated blast furnace slag (GGBS) m:30 to study the difference properties like work ability compressive strength and flexural strength test. Fresh and hardened concrete and also compare above properties with normal concrete. 1. In construction materials are making the idea of sustainable construction more believable everyday. In this paper GGBS & 5%, 10% weight cement and manufactured sand in concrete. 7 days and 28 days are has been done M:30 grade of concrete. 2. This research is carried 25% RCA 5% GGBS M.S 20%. This research is carried out in the phase. In M:30 grade concrete out to determine the 25% RCA 5% GGBS 20% M.S are optimum percentage of replacement at which maximum compressive strength is achieved.
