EXPERIMENTAL STUDY ON FRC BY PARTIAL REPLACEMENT OF CEMENT WITH SILICA FUME AND FLY ASH USING PEG-400

Abstract

In the construction industry, mainly the production of Portland cement will cause the emission of pollutants resulting in environmental pollution which is reduced by increasing the usage of industrial by products in cement. Industrial by product such as Fly Ash & Silica Fume are cementitious material used as partial replacement for cement in concrete to produce high strength in concrete. Curing in concrete plays a main role in developing strength of concrete and it helps in maintaining moisture content in concrete during its early ages in order to increase the required properties.A concrete curing agent forms a membrane over the top of the concrete while. This stops the water on the surface of the concrete evaporating too quickly and hence helps to reduce cracking and dusting. Since concrete curing agent manages the behaviour of water in the concrete. The present experiment is carried out to investigate the effect of different curing agents on FRC with replacement of cement by silica fume at 10% and fly ash as (20% & 30%). Tests to be conducted by adding 1% of steel fibers. And different dosages of curing agent polyethylene glycol-400 as (0.5%, 1% & 1.5%) weight of water.
