【摘要】 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。更多还原

【Abstract】 In order to improve carbonation resistance of high_addition flyash concrete,the grinding of flyash and additon of hydrated_lime in flyash concrete have been studied.It is shown that it is possible to improve the carbonation resistance of high_addition flyash concrete by using these methods without reducing its strength.更多还原
