摘　　要：主要研究不同黏土掺量对黏土-硅质石屑-水泥-石灰水热合成反应体系水热合成硬化体的抗压强度、比表面积、结合水量和pH值的影响。结果表明,黏土在水热条件下能参与体系的水热合成反应,在一定掺量范围内,黏土不仅没有降低硬化体的性能,反而有利于硬化体性能的提高。Experiments were made mainly for study on effect of different clay content upon performance of clay-siliceous crushed stone-cement-lime hardenite of hydro-thermal synthesis such as compressive strength,specific surface area,hydration water content and pH value. The result indicated that,clay can participate in hydro-thermal synthesis reaction of the system under hydrothermal condition,within the range of certain clay mixing amount,the clay not only does not reduce the performance of hardenite,but also help to improve the performance of hardenite.
