摘　　要：将玻璃粉作为辅助胶凝材料替代砂浆中部分水泥,其有利于提高拌合物流动性,同时不同颜色、不同粒径的玻璃粉对砂浆流动性影响有差异;将不同比例废玻璃渣替代混凝土中细骨料,随着废玻璃渣掺量增加拌合物流动性呈减小趋势,但仍符合规范最低要求;将废玻璃磨成较大颗粒替代混凝土中粗骨料,随着替代量增加拌合物流动性呈变大趋势,其有利于提高拌合物流动性。Through the experiment using waste glass as supplementary cementitious materials to replace part of cement mortar and the results show that it proposes to improve the liquidity of mortar. At the same time,different color and size have different influence on the liquidity of mortar. Experiment with different proportion of waste glass to replace fine aggregate in concrete and the results show that with increasing dosage of waste glass the liquidity of concrete presents a trend of smaller,but still meets the requirements of specification. Instead of coarse aggregate with grinding waste glass into larger particles,the experimental results show that as the alternative to increase the liquidity of concrete presents a trend of larger and it improves the liquidity of con-crete.
