摘　　要：以粉煤灰和天然火山灰分别作为掺合料,对比研究了对胶砂用水量、胶砂强度、胶材水化热的影响。结果表明:掺天然火山灰胶砂用水量较掺粉煤灰的高,胶砂强度较掺粉煤灰的低,胶凝材料水化热较掺粉煤灰的高,天然火山灰活性效应低于粉煤灰。With fly ash and natural pozzuolana as admixtures respectively,effects on water consumption of cementation sand,strength of cementation sand and hydration heat of cementation materials are compared and studied.The comparing and studying results show that water consumption of cementation sand admixed with natural pozzuolana is higher than that mixed with fly ash;strength of cementation sand with natural pozzuolana is lower than that with fly ash;hydration heat of cementation materials with natural pozzuolana is higher than that with fly ash;activity effect of natural pozzuolana is lower than that of fly ash.
