粉煤灰在高性能混凝土中的应用

本文通过正交设计,在高性能混凝土中掺入粉煤灰等量取代水泥,试验研究了强度等级为C50的高性能混凝土的配合比及测定了相应的混凝土性能,在分析讨论粉煤灰的掺量对高性能混凝土工作性及强度影响的基础上,指出了在配制高性能混凝土中掺入粉煤灰及高效减水剂双掺技术的技术途径,从而得到最佳配合比.

Fly ash in high-performance Concrete

In this paper,orthogonal design,in the same amount of high-performance concrete mixed with flyash to replace cement,experimental research,the strength grade of C50 high-performance concrete mix and measure the corresponding performance of concrete in the analysis and discussion fly ash content on high-performance concrete workability and strength of impact,based on that in the preparation of high-performance concrete mixed with fly ash and superplasticizer-doped technology,technical approach,to get the best...
