粉煤灰活化性能的试验研究

为了解决在水泥混凝土方面由于粉煤灰活性而引起利用率过低的问题,通过采用目前比较高效的粉煤灰活性激发剂FJ所配制的无熟料粉煤灰水泥的方法,取得了硅酸盐水泥标准强度可达175#以上,特别是早期强度发展很快可喜结果．并从几方面检验了活化粉煤灰的优良性能．结果表明,这是利用再生资源,保护环境的一条新途径。

Study on activation ability of coal ashes

In order to solve the problem that the low activity of fly ash leads to the low utility rate in manufacturing cement, some experimental results of activating fly ash are given in the paper.The results show that the clinker-free fly ash cement with activator FJ can satisfy the requirement in strength of 175#silicate cement and its early strength develops very quickly.The excellent behaviors of activated coal ashes are tested. The results showed that this is a new way of making use of scrap materials and protecting environment.
