为实现城市固体垃圾废玻璃资源化,以不同掺量废玻璃粉取代水泥,按标准试验方法研究了C30与C50两种强度等级的废玻璃粉混凝土(waste glass powder concrete,WGPC)各类强度变形指标.试验发现:C30WGPC在废玻璃粉掺量在25％～30％之间时,抗压强度同比降低幅度最大,达到了21.7％,C30WGPC替代水泥掺量可在0～25％以内,C50WGPC最佳掺量可大于25％;废玻璃粉的掺入改善了混凝土的脆性性能,随着试配强度等级的提高脆性会有所增大,C50WGPC轴压强度与抗压强度关系式可以近似地进行普通混凝土两者关系的换算;另外,WGPC弹性模量公式适用于计算普通混凝土的弹性模量,WGPC泊松比与普通混凝土泊松比相差不大.试验...

In order to realize the recycling of municipal solid waste glass, the various strengths and deformation indexes of C30 and C50 strength grades waste glass powder concrete (WGPC) were studied according to the standard test method by replacing cement with waste glass powder in different dosages. It showed that when the amount of waste glass powder was between 25%~30%, the decrease in compressive strength of C30WGPC was the largest, reaching 21.7%. The replacement of cement by C30 WGPC could be within 0~25% and the optimal blending amount of C50 W...
