Studies on strength behaviour of green self cured concrete with ecosand with impact of fly ash and ground granulated blast furnace slag

Abstract

Construction firms now use artificial sand or else manufactured sand in concrete for a day instead of natural river sand, where the excavation prohibition applies to river sand along with the implementation law. Natural sand or River sand are one of the constituents of concrete taken from a river. The problems of deterioration of the ecosystem and costly and the condition of the natural sand of river is rising day by day. About the Global Natural sand consumption has increased because of excessive use of concrete to ensure a very strong demand for river san, where Eco Sand is necessary to replace natural silica. Potable Water, meanwhile, is also the extremely ubiquitous feature for the concrete production and curing activity, and it is now insufficient for a limited period due to a superior growth in human population growth. Self-curing concrete helps to reduce the use of potable water, in contrast to the traditional curing system. In supplement to chemical admixture with the concrete mixture, this paper deals with the various studies of fresh and hardened concrete specimens with various replacement level of Eco sand and findings with the self-curing agent mixed with PEG 400 with Fly Ash and GGBFS proportioning. The results are correlated with the replacement of Eco sand with river sand with both ordinary self-curing concrete and blended self-curing concrete with M30 grade for the different combinations of blended proportions. Attempts have been made to research with Eco Sand to identify the properties of blended self-curing concrete.
