摘要
This paper deals with the repair of damaged, plain concrete and polymer cement concrete by impregnation with methyl methacrylate (MMA) or sulfur. The stress-strain (σ-ε) curves of the unaxial compression of the concrete before and after repairing were given. The results indicate that the strength of damaged concrete can be reinstated and even improved after the concrete is impregnated with MMA or sulfur. The main mechanism of repairing is that the cracks, the original pores and microcracks are filled with MMA or sulfur, and the im-pregnant plays role in adhesion enhancement and reinforcement.
