Abstract： The application progress of high titanium heavy slag in concrete was reviewed, and the effect regularity of high titanium heavy slag on working performance, mechanical property and volume stability property of concrete was emphatically expounded, and its influence mechanism was analyzed, in order to providing reference for the high value application of high titanium heavy slag in concrete. By comparing and analyzing the relevant research results of domestic and foreign scholars, it is found that the mechanical properties of concrete prepared with high titanium heavy slag can be improved, and pre-wetting treatment of high titanium heavy slag is beneficial to improve the working performance of concrete, as well as enhance its mechanical properties and reduce its drying shrinkage. Meanwhile, the durability of the concrete prepared with high titanium slag is equivalent to that of natural sand and stone, which can meet the durability requirements of concrete.

Keywords :  high titanium heavy slag;  working performance;  mechanical properties;  volume stability
