Abstract
In this paper,orthogonal test method is used to design the mixture ratio of punching and filling mortar mixed with admixtures and additive.By means of range analysis,hierarchical analysis and comprehensive scoring method,the typical factors such as water-binder ratio,cellulose ether content and fly ash replacement rate were analyzed,and the optimal mix ratio scheme was put forward.The mixed proportion mortar has great fluidity,meets the construction process requirements of the stone technology of filling mortar,and reaches the strength level of M20 mortar,which is technically feasible and economically reasonable.关键词
