Abstract: This paper describes the design of consolidation and strengthening qrouting material in microfissures, and also characters of MMA chemical qrouting material and its effect in application. MMA Chemical grouting material possesses the following advantages: The lower viscosity than that of water; hardening in -19^-23℃; non-contraction after hardening; the high strength and adhesion; the durability; the low toxicity and the non-pollution of the environment after its hardening. If we use MMA for bedrock consolidation grouting, the parameters of weakly weathered rock can be lifted to the level of slightly weathered or fresh rock. If we use MMA for strengthening grouting of fissured concrete, the integrity of concrete can be recovered.
