大掺量粉煤灰混凝土在大体积承台中的应用研究

Application Study of Large Amount of Fly Ash in Large-area Concrete of Cushion Cap

从降低混凝土水化热的角度,研究了如何使用大掺量粉煤灰配制大体积混凝土配合比,以达到工作性优良、力学强度高、绝热温升低的效果,为大体积承台混凝土施工提供有力保障。

This paper studied how to prepare the proportion of mass concrete by the large amount of fly ash,from the point of reducing hydration heat of concret,in order to achieve the effect of excellent workability,high mechanical strength and low adiabatic temperature rise.This provided a strong guarantee for the construction of mass cap concrete.
