Experimental Study on Mechanics Performance of Complex High Titanium Heavy Slag Concrete

In view of the present situation that the preparation of complex high titanium heavy slag concrete (hereinafter referred to as CHTHSC) by using all coarse aggregate, fine aggregate and ground admixture made of high titanium heavy slag, is in need of experiments and studies in detail, this paper, based on the verification and analysis of structural stability of complex high titanium heavy slag and through tests of preparing CHTHSC from C10 to C55, compares CHTHSC with ordinary concrete and high titanium heavy slag concrete (hereinafter referred to as HTHSC) from three aspects of mixture amount of coarse aggregate, fine aggregate and composite powder. Results show that the compression resistance, axial compression resistance and cleavage strength of CHTHSC are higher than those of the other two kinds of concrete. For CHTHSC, it is appropriate to have composite powder take the place of 15%-20% of cement content.
