Experimental Investigation on the Mechanical Properties of Self Cured Blended Concrete

Abstract

Concrete is the most frequently applied material in construction nowadays, because of its compressive strength and durability. Cement, fine aggregate, coarse aggregate, and water are mixed in particular amounts depending on the nature of the work to generate plain concrete. Conventional concrete requires a pleasant environment in which moisture is provided for a minimum of 28 days in order to hydrate properly and achieve the necessary strength. Concrete's strength properties will be harmed if the curing process is sloppy. Concrete's strength is determined by how long it takes to cure. Improper curing is the cause of cement hydration, which can be efficiently rectified by employing self-curing concrete. Polyethylene glycol (PEG 400), a water-soluble polymer self-curing agent, was used to cure the SC mixtures. Concrete's strength and serviceability can be improved by using the correct amount of self-curing gels. In this investigation, PEG by weight of cement was varied in M40 grade concrete from 0.5 percent to 0.5 percent, 1 percent, 1.5 percent, and 2 percent, and standard concrete was analyzed. This paper also covers the compressive strength, flexural strength, and tensile strength tests of blended concrete using self-curing concrete.
