Sažetak

The waste blast furnace slag generated during the steelmaking process is used as the basic material, and an appropriate amount of fly ash is added to conduct shear tests to obtain the shear mechanical indicators of the fly ash blast furnace slag mixture, thereby obtaining the strength mechanical properties of the mixture. The test results show that there are few fine particles in the mixture, which is not enough to affect its shear mechanical properties, so the water content has little effect on the shear strength of the mixture, and the mixture has good water stability; In the shear test, it can be found that the greater the normal stress, the greater the initial shear shrinkage, and the smaller the later shear expansion. After the normal stress exceeds 150 kPa, the shear expansion significantly decreases.
