ABSTRACT

In order to effectively use the solid waste red clay in Chongqing to carry out the basic erosion protection of the local cross-river bridge, the curing agent and cement are used to improve the performance of Chongqing red clay, the influence of curing agent and water-solid ratio on the permeability coefficient, unlimited compressive strength and drainage rate of curing soil is mainly studied. The test results show that the increase of curing agent can significantly improve the impermeability through the mechanism of forming three-dimensional network structure to block the pore channel; the increase of water-fixed ratio will significantly reduce the impermeable performance, and the mechanism is that free water weakens the particle bonding and forms the seepage channel. In terms of mechanical properties, the curing agent has an optimal value (0.3%); the rise of water-solid ratio will weaken the bonding between particles and reduce the compaction of cured soil, resulting in the reduction of unlimited compressive strength. In terms of bleeding performance, the bleeding rate was zero when the amount of curing agent was 0.2%, and the water-solid ratio had no significant effect on the bleeding rate.
