摘要
在掺合料对碱-硅反应的抑制机理基础上,根据不同矿物掺合料对碱-硅反应的抑制试验结果,比较并分析了四种掺合料对碱-硅反应的抑制效果。结果表明,硅粉对混凝土碱-硅反应的抑制效果最好,当硅粉掺量为15%时,抑制率可超过90%;粉煤灰和石灰石粉的抑制效果次之,而矿渣的抑制效果相对较差。
Besed on the mechanism of restrainting the alkali-silica reaction by using of mineral admixtures, the effects of four admixtures have been compared experimentally. The rezults show that the best one is silica fume, its long time＇s restrainting rate can be over 90% when the content of it is in 15%, and the effects of fly ash and limestone powder are in second-rate, while the slag powder is the worst one.
