摘  要：为研究废玻璃粉混凝土的抗碳化性能，将中位粒径为9.45μm、16.38μm和25.15μm 的三种废玻璃粉分别等质量取代10%、20% 和30% 的水泥制成混凝土试块，在标准条件下养护3d、28d、56d 后，测得各龄期下各试块的抗压强度以及加速碳化至3d、7d、14d、28d和56d 的碳化值，并通过压汞法和扫描电镜（SEM）测得试块内部孔径分布和微观形貌。结果表明，标养3d 时，中位径16.38μm 的废玻璃粉更有利对大孔细化，混凝土早期密实度高，抗碳化能力更佳；标养56d后，中位径为9.45μm 废玻璃粉掺量≤10% 时，试块强度和碳化深度与基准组相当。

Abstract: In order to study the carbonation resistance of waste glass powder concrete, the concrete specimens with 10%, 20% and 30% cement were replaced by three kinds of waste glass powders with the median particle sizes of 9.45μm, 16.38μm and 25.15μm, respectively, and ofter the standard curing for 3d, 28d and 56d, The compressive strength and the 3d, 7d, 14d, 28d and 56d of carbonization value of the samples under various curing conditions were measured. The pore size distribution and microstructure were measured by mercury intrusion and scanning electron microscopy(SEM). The results shows that when the standard specimen curing is 3d, the median diameter of 16.38μm waste glass powder is more conducive to macropore refining, concrete early high-density, better anti-carbonation ability. After 56d of standardicuring, when the dosage of waste glass with the median diameter of 9.45μm is less than or equal to 10%, the strength and carbonation depth of the specimen are equivalent to the reference group, which shows that in the waste glass powder concrete, the appropriate content of waste glass powder, particle size and curing age can improve the compressive strength and carbonation resistance.
