| Abstract: | This paper deals with the preparation of composite phosphate modified sodium silicate binders and sand mined method and its properties. The results of experiments show that phophate, organism K can be improved the ordinary temperature strength and lower the high temperature retained strength of silicates sand mixture, improving its collapsibility. |
