Quadruple blend (cement, fly ash, slag and ultra-fine slag) for mass concrete for high-rise construction buildings

摘要

Concrete generates heat as the cementitious material hydrate and for thin sections; heat dissipates almost as quickly as it is generated. In case of massive structures, temperature increases due to generation of more heat of hydration therefore management of concrete temperatures is necessary to prevent damages, minimize delays and meet specifications. This study was carried out at one of the multistoried residential building of height 325 meters. The main concept of this study is to minimize concrete core temperature and differential temperature of high performance M80 grade of concrete and address durability concerns and pump ability of concrete with low viscosity.
