【摘要】 分析了鄂西南地区页岩的化学成分和矿物成分，利用强度试验法研究了不同煅烧温度和时间下页岩的火山灰活性，指出烧页岩的火山灰活性来自其中的粘土矿物在分解之后所形成的无定形物所处的状态，确定了该页岩获得最高活性的煅烧温度和时间分别为７５０℃和０．５ｈ，从而为该页岩的实际应用提供了重要的理论依据更多还原

【Abstract】 The chemical composition and mineral component of shale which lies in the southwest of Hubei province have been analysed in this paper.The pozzolanic activities of burnt shale under different burnt tempreture and time have investigated by the means of strength test.It is concluded that the cementitious activity of the burnt shale depends on the state of the amorphous substances coming from the decomposition of clay minerals.The suitable heating tempreture and time are 750℃ and 0.5 hour,for acquiring the greatest cementitious activity of this shale.更多还原
