高温高湿环境大体积粉煤灰混凝土选材及配合比设计

Selection of Materials and Mix Design of Mass Fly Ash Concrete Under High Temperature and Humidity

从大体积混凝土原材料研究入手，针对大体积混凝土实际所处的高温高湿环境，紧紧围绕如何最大限度地降低水化热，选取符合实际工程需要的大体积混凝土原材料，并对大体积粉煤灰混凝土配合比进行设计，最终得到了满足高温高湿特殊环境要求的大体积混凝土配方．

This paper starts with a study of the raw＇ materials for mass concrete, and states that hydration heat should be reduced to the least under the environment of high temperature and humidity, and that the selection of raw materials should be determined by practical need. The paper also makes a design of the mix ratio of mass fly ash concrete, and finally works out a compounding of mass concrete for environment of high temperature and humidity.
