| Abstract: | In this paper, with the testing comparison and mechanism analysis of technical features such as compression strength, impermeability and frost resistance of fly ash concrete(FAC) ,the economic mixing ratio of FAC according with the norm of seepage control project of canal is raised to offer scientific foundation for the application of the project technology .By using synthetic agent of concrete ,the key technology of low early strength and the difficulty of rapid shapping of thin wall of concrete with large volume and substandard fly ash is solved. With the premise of ensuring compression strength, frost resistance and impermeability, the FAC could save about 40 percent of cement and 15 percent investment. |
