【Abstract】 In this paper, the effect of two types of expansive agents on the shrinkage performance of high strength concrete with high fluidity was discussed, and the effect on the mechanical properties was also studied. The results show that the composite use of calcium sulphoaluminate calcium oxide expansion agent and magnesium oxide expansion agent has no adverse effect on the mechanical properties of high strength concrete with high fluidity, and the shrinkage performance is improved.更多还原
