推行优生混凝土提高水泥强度效益

Promote “optimized concrete”，increase cement strength benefit

文章引入“优生混凝土”概念，并对各强度等级的现用混凝土配合比的试验数据进 行了统计分析，得出了相应的水泥和胶凝材料的强度效益，论证了通过合理选用原材料、科 学使用活性矿物掺和料、合理选用减水剂等技术途径可以提高水泥强度效益。

In this article,the concept of 'optimized concrete' is introduced,a nd statistical analysis to the experiment data of the concrete proportioning rat ios used for each strength grades is made,and the strength benefit of the corres ponding cement and cementing material is achieved.The author believes that the c ement strength benefit could be increased with technical measures such as reason able raw material selection,scientific application of active mineral mixing agen t,reasonable selection of water reducing agent etc.
