根据影响混凝土碳化的主要因素和粉煤灰混凝土的特点，研究了对粉煤灰进行磨细和增加适量熟石灰的措施，在不降低粉煤灰混凝土强度前提下，探讨改善大掺量粉煤灰混凝土抗碳化性能的可行性。
According to the main factors influencing the carbonization of concrete and the characteristics of fly ash concrete, the measures to grind fly ash and increase the amount of hydrated lime are studied. The improvement of large-volume fly ash is discussed without reducing the strength of fly ash concrete. Feasibility of anti-carbonation performance of concrete.
