Study on Long-Term Deformation and Durability of Complex High Titanium Heavy Slag Concrete
Taking the C30 complex high titanium heavy slag concrete (hereinafter referred to as CHTHSC) as example, this paper makes experiments and researches its performance on the long-term deformation and durability. The results show that, the CHTHSC will not lead to the problem of volume stability, and its shrinkage strain and creep meet the design standards. The CHTHSC shows no alkali- aggregate reaction, and its impervious grade, carbonation depth, Chloride ion diffusion coefficient, sulfate corrosion resistance coefficient meet the design requirements for concrete durability. The investigation on the durability of projects with the CHTHSC shows that the compression resistance of concrete in their cores is higher than design strength, with outward appearance unchanged. The experiment results provide important reference for the application of this kind of concrete.
