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.

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 offer the standard caring 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 e...
