Experimental Investigation on Mechanical Properties of Self Curing High Strength Concrete

Abstract

Concrete is very important in construction industries. For a well developed country we need industrial buildings, residential building, educational building business building, bridges, culverts, dams etc. To construct such structures concrete is most required material. Now-a- day’s large amount of concrete is producing for constructions. For mixing of concrete water is mandatory without water we can’t mix the concrete. The concrete is mixed along with polyethylene glycol in the range 0.5%-1% additionally mixed with admixtures like super plasticizer and silica fume which give more strength and workability for the concrete. In this study involves along with concrete the admixture polyethylene glycol (PEG4000) is added. The affect of adding (PEG 4000) on compressive strength, split tensile test, and modulus of elasticity by different percentage of PEG i.e.(0.5%, 1%, 1.5%) were studied for M70 and M80 grades.By observing the results that the optimum dosage age of PEG is 1% for both M70 and M80 grades. When compared with conventional concrete strength wise self curing concrete achieving maximum strength and also don’t required water for hydration of concrete.
