碳化性能是混凝土的重要耐久性指标之一,而水泥细度对混凝土的碳化性能有重要的影响。本文主要研究了水泥细度对混凝土抗碳化性能的影响。试验结果表明:水泥细度的提高有利于混凝土抗碳化性能的提高,并探讨了水泥细度对混凝土碳化性能影响的作用机理。 Carbonization performance is one of the important durability indicators of concrete, and the fineness of cement has an important influence on the carbonization performance of concrete. This paper mainly studied the effect of cement fineness on the carbonation resistance of concrete. The test results show that the improvement of cement fineness is beneficial to the improvement of carbonation resistance of concrete, and the mechanism of the effect of cement fineness on the carbonization of concrete is also discussed.
