本文研究了粉煤灰内掺石灰岩粉外掺对混凝土工作性能、力学性能和耐久性能的影响。结果表明:采用粉煤灰和石灰岩粉高性能混凝土比普通混凝土具有更好的工作性、匀质性、易密性,且混凝土光亮度具有大理石效果,混凝土强度和耐久性等指标均能满足规范要求。高性能混凝土能消除普通混凝土的质量通病。 This paper studies the effect of fly ash mixed with limestone powder on concrete performance, mechanical properties and durability. The results show that the high-performance concrete with fly ash and limestone powder has better workability, homogeneity and compactibility than ordinary concrete, and the concrete brightness has the marble effect, and the concrete strength and durability can meet the specifications Claim. High-performance concrete can eliminate the common quality of ordinary concrete.
