The raw materials commonly used in paste materials include coal gangue, fly ash and cement cementing materials. The physical and mechanical properties of paste were closely related to the basic properties of raw materials. The basic properties of Xingtai coal gangue and Matou power plant fly ash were analyzed. In the coal gangue, a relatively large amount of minerals are in kaolinite, quartz, mica, albite, fly ash was grade II fly ash. Taking slump as the standard, two ratios were determined, and the parameters such as setting time, strength and bleeding rate were measured. The results showed that the slump values of the ratio A and B were 215 mm and 202 mm respectively, and the bleeding rates were 3.5 % and 3.2 % respectively. The setting time was between 4 ~ 5h and 5 ~ 6h respectively, which could meet the requirements of paste pumping and solidification, and could be selected according to the needs of the site.
