摘要:
采用ISAT（initial surface absorption test）方法测定混凝土的吸水性，研究水灰比，及粉煤灰和硅灰两种矿物掺合料对混凝土毛细吸水性的影响.试验结果表明，降低水灰比能大幅降低混凝土吸水性，粉煤灰及硅灰等掺合料能减少水泥石中毛细孔数量，使混凝土吸水性减小，且粉煤灰与硅灰复掺具有叠加效应.
Abstract:
This paper studies the effects of water-cement ratio，two mineral admixtures of fly ash and silica fume on the water sorptivity of concrete by initial surface absorption test method． The experimental results show that the sorptivity of concrete decreases with decrease in the water-to-cement ratio of concrete and replacement of cement by fly ash or silica fume． And it has superimposed effect when the fly ash and silica fume are used together in concrete．
