| 摘 要： | 试验研究了矿渣微粉对混凝土强度和抗冻性能的影响.结果表明,同基准混凝土相比,掺入20%～50%比表面积为475m2/kg的矿渣微粉,可以明显提高混凝土的后期强度,并降低冻融循环后重量和动弹性模量的损失率.这说明矿渣微粉对混凝土具有显著的增强作用,并对混凝土的抗冻性能具有很好的改善作用.

| Abstract: | The effect of ground granulated blast furnace slag(GGBS) on strength and freezing-thawing durability of concrete is studied.The results show that compared with normal concrete,by adding 20-50% GGBS with 475m 2/Kg special surface the strength of concrete can be apparently improved and the loss ratio of weight and moving modulus of elasticity of concrete can be reduced after freezing-thawing cycles.It is shown that GGBS may increase the strength of concrete and improve freezing-thawing durability of concrete. |
