摘要
为降低玻璃对环境的危害以及水泥生成过程中产生的能耗,文中通过测试玻璃粉对工作性能以及耐久性能的影响,并运用XRD、SEM、MIP等微观分析方法探究机理,研究发现玻璃粉部分替代水泥有助于改善混凝土的工作性,但由于玻璃粉的替代,导致水化的胶凝材料的减少,孔隙率增加。随着龄期的增加,玻璃粉的火山灰反应有利于降低有害空隙,在适量掺加条件下,玻璃粉掺入对水泥基材料有利。
In order to reduce the environmental hazards of glass and the energy consumption generated during cement generation,the effect of glass powder on workability as well as durability performance was tested,and the mechanism was investigated using microanalysis methods such as XRD,SEM,and MIP.It was found that the partial replacement of cement by glass powder helped to improve the workability of concrete,but the replacement of glass powder led to the reduction of hydrated cementitious material and the increase of porosity.With the increase of the age,the volcanic ash reaction of glass powder facilitates the reduction of harmful voids,and the incorporation of glass powder is beneficial for cementitious materials under proper participation conditions.
