Research on properties of high performance concrete of mine shaft construction
Using the empirical value test and water reducing rate combination mode, high performance concrete of mine construction was prepared with different concrete admixture for the same strength concrete. Different admixtures of concrete fluidity, setting time and basic mechanical properties of concrete were detected. Experimental results indicate that compressive strength, tensile strength and bending strength of high performance concrete have been also improved. Moreover the ratio of flexural strength increases most among three. High performance concrete admixture for high performance is feasible to the concrete strength range from C30-C70. High performance concrete admixture testing standards need to be established.
