双掺减水剂与粉煤灰混凝土减水率的简易检测方法

A Simple and Easy Test Method of Water-reducing Rate of Concrete Mixed with Water-reducing Agent and Fly Ash

采用检测水泥净浆流动度的方法,来推算出混凝土在不同粉煤灰和减水剂掺量下的减水率,可大大减少试验工作量和劳动强度,简易可行,加快了提供混凝土配合比设计参数的速度。作者结合所在的电站工程,对该方法进行了初步验证。

The calculation of water - reducing rate of concrete mixed with different quantity of fly ash and water - reducing agent by monitoring flowability of cement net grout can greatly reduce both load and intensity of work, which is simple, easy and workable, speeding up providing of mix design parameters of concrete. The authors have tentatively verified the above - said method according to the practical condition of the project.
