减少宝峰水库坝体混凝土水泥用量的应用研究

A Applied Study on Reducing Cement of Concrete in Bao-Feng Dam

减少坝体混凝土的水泥用量，不但能降低工程造价，而且还可以保证工程的质量，本文主要介绍：采用最大容量法的混凝土配合比试验方法、掺入煤灰和减水剂以及施工工艺控制等综合措施，达到了既保证工程质量又节约１１４４吨水泥的效果。

This paper introduces the method of maximum density in desinging the mixing proportion of a concrete dam, and at the same time by the comprehen - sive measure of using a suitabe amount of pulverized fly ash together with wa- ter reducing admixcure, to improve the workability of the fresh concrete and various properties of the hardened concrete. As a result, not only the good quality of concrete can be insured, but also 1144 ton of cement have been economized.
