| Abstract: | Aiming at the method of strengthening member with steel wire mesh and polymer mortar,the influences of superplasticizer,polymer,fly ash,silica fume and expansion agent to workability 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 properties,and the optimal polymer modified mortar mixing ratio was proposed. |
