摘要
通过对超细粉煤灰 (SPFA)和常规粉煤灰 (PFA)减水性能的对比试验 ,发现SPFA具有良好的减水性能 ,并通过大量的掺加SPFA和PFA的混凝土试验配合比得到证实。对混凝土抗压强度发展趋势的分析表明SPFA作为水泥替代材料具有良好的胶凝性能 ,可将其应用于高强高性能混凝土中。
The high ability of water reduction of SPFA is found through a parallel test of water demand with PFA and is proved by a variety of trial concrete mixes with SPFA and PFA.Analysis on compressive strength development of concrete are shown that SPFA has a very good cementing effect,thus it can be used in high strength high performance concrete.
