Experimental Study of Soft Rock Polymer Cement Solidification

The paper background is based on the soft rock slope of Yizhou--Liuzhai highway in Guangxi province. Polymer cement curing agents are used to reinforcement the soft rock slope to prevent or slow the soft rock slope softening and disintegration, improve long-term stability of soft rock slope engineering. By hydrophobic test, waterproof test, firmness experiments, the effect of coating modification experiments after polymer cement curing soft rock to study the effect of polymer cement curing agent. The results show that: through the polymer cement curing, soft rock surface wetting angle increased from 37.5 degrees to 82.9 degrees, good fastness, seven days of water absorption decreased by 1.9% to 0.42%, pore area per unit area of soft rock dropped from 6.54 to 3.71.
