摘 要：<正> This paper deals with the repair of dam-aged plain concrete and polymer cement concreteby impregnation with methyl methacrylate（MMA） or sulfur.The stress-strain（σ～ε）curves of the unaxial compression of the con-crete before and after repairing were given.Theresults indicate that the strength of damagedconcrete can be reinstated and even improved af-ter the concrete is impregnated with MMA orsulfur.The main mechanism of repairing is thatthe cracks,the original pores and microcracksare filled with MMA or sulfur,and the im-pregnant plays role in adhesion enhancement andreinforcement.
