| Abstract: | 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. |
