Abstract:  Aiming at the method of strengthening member with steel wire mesh and polymer mortar, the irdluences of superplasticizer, polymer, fly ash, silica fume and expansion agent to vxorkability and mechanical properties of the mortar were studied. The test results indicated that the mortar modified by the several materials had better workable and mechanical pmperties, and the optimal polymer modified mortar mixing ratio was proposed.
Keyrwrds:  polymer modified; mortar; structural strengthening
