Control of Delayed Enttringite Formation in the Mass Concrete inTaishan Nuclear Power Plant

Abstract

Abstract: The proper evaluation of the delayed enttringite formation (DEF) in the mass concrete is an important index of the duration of mass concrete in the nuclear power plant construction. In order to control or minimize the delayed DEF in the mass concrete, the mix design of the specific concrete is evaluated. The preliminary test simulations are performed to find the technical measures that minimizing the DEF. Under any condition, the highest temperature in the center of the mass concrete should not exceed 80 degrees celsus.

Key words: Mass Concrete, Delayed Enttringite Formation, Simulations
