摘要
在评价普通混凝土常用抗冻性试验方法及评价指标的基础上,针对多孔混凝土的结构特征,对多孔混凝土的冻融破坏机理进行分析,探讨现行多孔混凝土的抗冻性试验方法和评价指标的不足,进行多孔混凝土冻融试验,并建立动弹性模量与抗弯拉强度之间关系,以便为其在具体实践中的应用提供依据。
On the basis of evaluating test methods and evaluating targets for the resistance of common concrete to freezing and thawing, test methods and evaluation targets for resistance of porous concrete to freezing and thawing are explored and analyzed in the paper, with the structural characteristics and the freezing-and-thawing damaging mechanism of porous concrete analyzed, ahd the current test methods and evaluation targets for resistance of porous concrete to freezing and thawing as well as their shortcomings commented on. Then the relationships of modulus of elasticity and flexural-tensile strength are established to provide a scientific basis for their practical application.
