摘要
文章采用正交试验方法对高性能混凝土强度的影响因素进行了深入研究。研究结果表明：水胶比、粉煤灰取代率是影响混凝土的主要因素，砂率对混凝土的强度影响不大，但影响混凝土的流动性。
The paper had a detail research on the factors effected to the high performance concrete strength with perpendicular test method. The research results showed that the water gel rate and fly ash replacement rate are the main factors effected to the concrete and the sand rate has a less influence to the concrete strength, but has an influence to the flow property of the concrete.
