摘　　要：研究了高钙粉煤灰对硬化水泥浆体耐硫酸盐性的影响。结果表明 :随浸渍龄期延长 ,高钙粉煤灰硬化水泥浆体的耐硫酸盐性一般变差 ;高钙粉煤灰硬化水泥浆体的耐硫酸盐性与硫酸盐溶液的种类、浓度有关 ;In this paper, the effects of high calcium fly ash on hardened cement paste were researched. The results show that the resistance to sulfates will decrease as the time is passing. The resistance to sulfates is related with the kind and concentration of the sulfate solution. And the addition of gypsum may also affect the resistance to sulfates of hardened cement paste with high calcium fly ash.
