摘要
采用不同的激发剂和激发方式,研究了粉煤灰高性能混凝土的流动性。结果表明,采用硫酸盐和熟石灰复掺与粉煤灰共同磨细,或硫酸盐与粉煤灰共同磨细的激发方式,均能使混凝土有较好的流动性能,且两种方式的效果相当。
By using different stimulators and stimulating methods, a research of the fluidity of the high- performance fly- ash concrete is made in this paper. The results show that by mixing sulfate and hydrated lime with fly ash for fine grinding or single activator - doped with sulfate, better fluidity of concrete can be achieved ,and the effects of the two methods make no much difference.
