Studies on strength parameters of blended self cured concrete with natural and manufactured sand on the impact of fly ash and ground granulated blast furnace slag

Abstract

Construction companies now use manufactured sand instead of natural river sand in concrete for a day, where the exploration limitation applies to river sand along with the implementation rule. Water, meanwhile, is also the most prevalent aspect of the concrete manufacturing curing process, and it is now scarce for a few days due to a greater rise in human population growth. In contrast to the traditional curing process, self-curing concrete minimizes the use of potable water. In addition to chemical admixture with the mixture, this paper deals with the various studies of fresh and hardened concrete specimens and findings with the self-curing agent mixed with PEG 400 with Fly Ash and GGBFS in different proportions. The results for the various combinations of blended proportions are correlated with the substitution of manufactured sand (M-Sand) with river sand with both ordinary self-curing concrete and mixed self – curing concrete with M30 grade. Attempts have been made to study the properties of blended self – curing concrete with Manufactured Sand.
