| 1. | The test result shows that the water binder ratio is the chief factor in damaging point . the saturation of concrete and the higher degree of saturation in the surface layer of specimens can be used to explain the damage form of specimens in the freezing - thawing , which include change of relative dynamic modulus of elasticity and weight
通过测定饱水受冻6次后混凝土试件的相对动弹性模量,可以计算出混凝土破坏时( e6 / e0 = 60 % )相对应的水饱和系数,即极限水饱和系数,试验结果表明对试件极限水饱和系数而言,水胶比影响显著。 |
