Researches on Properties of Polymer Modified Rapid Hardening Sulphoaluminate Cement Repair Mortar
The effects of different content of rubber powder, silica fume, cellulose ether, dihydrate gypsum, water reducing agent , defoamer on the dry-mixed mortar were studied according to orthogonal experiments. The results show that the compressive strength of 1 d is up to 38.4 MPa and the flexural strength to 6.4 MPa. Therefore the super-high mortar studied is mainly used for rush repairing engineering. It has great economical benefit and society benefit.
