C80级高性能泵送混凝土的耐久性试验研究

Experimental research on the durability of the C80 level high performance pump concrete.

本文通过试验试配及相关参数配制了C80级高性能泵送混凝土,并对其力学性能、工作性及耐久性能进行了试验研究。结果证明.本试验所配制的C80级混凝土具有良好的工作性,无开裂现象,收缩很小,具有较强的耐硫酸盐侵蚀性、抗渗透性、抗冻性及耐钢筋锈蚀性。

In this paper,the C80 level high performance pump concrete was made through the experiments to match and the related parameter,and the experiments to test its mechanical properties,workability and durability were also done.The results indicate that the C80 level concrete has the good workability,and there were no cracks,and its shrinkage was very small,and it has strong performances on the sulfate corrosion resistance,the impermeability,the frost resistance and the steel bar corrosion resistance.
