Study On The Compounding And Performance Of New Type Banding Mortar

In order to overcome the disadvantages of traditional binding mortar, In this paper new type binding mortar, has been developed in the paper, by adding polymer into mortar to improving the wetting binding strength and durability of mortarThe key techniques of compounding binding mortar are how to reduce the polymer-cement ratio of binding mortar, and how to improve the creak resistance of binding mortar. The paper has made a penetrating study on them. Selecting suitable technic for preparing the binding mortar and suitable mixture successfully reduces the polymer-cement ratio of binding mortar. And adding polypropylene fiber in binding mortar, its toughness and crack resistance improves obviously. Based on the study result, the paper has made a systematic study on the compounding and performance of binding mortar. Compared with tradition binding mortar, this new type binding mortar has better performance of water resistance, frost resistance and crack resistance, etc.
