掺加掺合料高强高性能混凝土的材料性能试验研究

Experimental Stuty on Material Performance of High Strength and High Performance Concrete About Mixing Material

通过对掺加不同掺合料的高强高性能混凝土的材性试验研究,说明了双掺比例合适的掺合料对高强度混凝土的工作度有所改善、抗压强度有所提高;在其他条件不变的情况下,砂率的提高对高强度混凝土的工作度有所改善、对高强度混凝土的抗压强度有所降低,确定了最佳砂率范围.

Through the experimental stuty of high strength and high performance concrete added in different type of mix, it is explained that the workability of high strength concrete was improved and the compressive strength of high strength concrete was enhanced because of adding double mix in appropriate proportion ,Under the with the other condition same, the workability of high strength concrete was improved and the compressive strength of high strength concrete was reduced because of increasing the sand coarse aggregate ratio. The optimum range of sand coarse aggregate ratio was defined.
