摘 要:为了探究利用废玻璃制备的可控低强度材料(CLSM)的性能,通过玻璃粉替代水泥,玻璃砂替代河砂设计正交试验,对试验结果进行极差分析和方差分析。流动度经时损失与玻璃粉掺量成反比;泌水率主要影响因素为玻璃粉掺量;早期抗压强度主要受到玻璃粉和玻璃砂掺量因素影响,经过28 d水化基本完成后,抗压强度受到玻璃粉掺量和质量浓度因素影响。最优配合比:胶砂比1∶4,GP掺量65%,GS掺量50%,质量浓度84%,粉煤灰占胶凝材料10%,减水剂占胶凝材料0.5%,消泡剂占胶凝材料0.3%。In order to investigate the performance of controlled low-strength materials(CLSM)prepared by using waste glass,orthogonal tests were designed by replacing cement with glass powder and river sand with glass sand,and the test results were studied by range analysis and variance analysis.It is shown that the loss of slump flow degree through time had an inverse relationship with the amount of glass powder admixture;the main influencing factor of bleeding ratio was the amount of glass powder admixture;the early compressive strength was mainly influenced by the factors of glass powder and glass sand admixture,and after the basic completion of hydration in 28 days,the compressive strength is influenced by the amount of glass powder and mass concentration.The optimal matching ratio was selected as 1∶4,65%of GP,50%of GS,84%of mass concentration,10%of fly ash,0.5%and 0.3%of water reducing agent and defoamer respectively.
