| Abstract: | The comprehensive thermos method was used for concrete construction within -2℃-19℃ in winter with the early strength compound-admixture. The grade of strength was ranged from C20-C40, and the concrete was mixed with or without fly ash. This article presented the results about the frozen critical strength of concrete. |
