采用比表面积为１４０００ｃｍ２／ｇ的超细磨粉煤灰和高效减水剂配制出坍落度２４３ｍｍ，２８ｄ抗压强度１０８．５５ＭＰａ，１８０ｄ抗压强度１４０．４ＭＰａ的超高强高性能混凝土。对用原状粉煤灰、硅灰、超细磨粉煤灰分别作混凝土的掺合料进行了性能对比，指出超细磨粉煤灰既有粉煤灰本身的“滚珠轴承”润滑作用和火山灰反应增强作用，又有硅灰的填隙挤水和密实增强作用。 Super-high-strength and high-performance concrete with a slump of 243mm, 28d compressive strength of 108.55MPa and 180d compressive strength of 140.4MPa was prepared using superfine pulverized coal ash with a specific surface area of ​​14000cm2/g and superplasticizer. The performance comparison of fly ash, silica fume and ultra-fine pulverized coal ash as concrete admixtures were performed respectively. It was pointed out that ultra-fine pulverized coal ash has both “ball bearing” lubrication and ash of fly ash itself. Reaction enhancement, silica flocculation squeezed water and compact reinforcement.
