Abstract: | This paper presents the preparation technology of high-strength self-compacting concrete (SCC) containing ultrapulverized fly ash (UPFA) and superplasticizer (SP). After selecting the parameters of mix proportions, a SCC with good workability, high mechanical properties, and high durability is developed. The experimental results indicate that the fresh mixture has low slump loss. The compressive strength of concrete reaches 80 MPa, and the concrete presents low permeability, good freeze-thaw resistance, and low drying shrinkage. |
