Abstract

Recently, serious cracking problems have been reported in this country while the process of actual massive concrete construction. he hydration heat arising from the chemical reaction of cement with water causes temperature differentials in between inside and outside of a structural member, and these temperature differentials induce thermal stresses. In this paper, we described on the practical application and quality control of the mass concrete mixed with fly-ash. This project is investigating adiabatic temperature rise test of concrete, mock-up test in the laboratory, ad B/P before placing the mass concrete in site. As a result, we can be prevent temperature cracking from the cement hydration heat of mass concrete and also can be showed up secure quality control flow chart of mass concrete.
