Self-Cured High Strength Concrete-An Experimental Study

Abstract

The effect of elevated temperature and durability studies is studied on fifty-four numbers of self-cured high strength concrete cubes of 100mm size with ultrafine mineral admixture, Alccofine 1203. Optimum dosage of internal curing compound and Alccofine used is 0.25% and 10% respectively. Non-destructive, elevated temperature, and durability studies are conducted on the specimens. Between the temperatures 100⁰C to 900⁰C, the percentage of loss in weight is found to be decreased. But, compressive strength is increased at 300⁰C and decreased at higher temperatures. The weight and compressive strength are increased for the cube specimens due to the specimens immersion in Sulphate, Chloride and Alkali solutions and Sea water respectively.
