Freezingandthawingtest shows that the figuration and cross-section of cement-based materials (paste, mortar and concrete) are different after they damage because of their different pore structures.
This paper expounds origin and mechanism of concrete of freezingandthawing destroy. The test result validates that silicon powder have great impact on concrete frost resistance.
