Abstract

In order to study the durability of gangue paste, the cement, fly ash and gangue were mixed with the proportion of 1:4:6 to compose paste and the mass concentration was 74%. Anti-erosion, anti-permeability and heat stability of filling body after 28d’s maintenance were tested. The results showed that filling body had a good anti-erosion for alkali while the acid and salt had large influence on initial strength of filling body. Filling body’s anti-permeability grade was P6 which stood for weak grade. Under the temperature of 30 and 60 , compressive strength of filling body increased slightly while it declined greatly under the temperature of 90 120 and 150 , heat stability was bad. The paste was suitable for north mines and deep mines with higher temperature.
