The Study for Concrete Frost Resistance Durability under The Action of Multiple Factors

摘要

The crack under the action of non-load was the most significant factor to affect the concrete frost resistance durability. The Orthogonal Experimental Design (OED) Method was used in this paper to optimize the match ratio of the additive and to increase the concrete frost resistance durability by adding the PF, the FA, the WA in the concrete and replacing the cement of ordinary silicate with the compound cement. It offers the reference value to the development of the hydraulic concrete.
