The results are listed as following :㏕he best anti-erosion proportion of resin present is 25wt% in the condition of silicon carbide reinforced SMCC, while the alumina reinforced SMCC is 40wt%.(2) The better anti-erosion results was achieved with the ratio of silicone resin to acrylic resin containing hydroxy being 3: 1.㏕he composites coating tends to be more brittle when added in alundum particles. It also means that the maximum erosion peak of alundum reinforced SMCC tends to normal angle.甌he change of erosion rate of SMCC can be divided into two stages with the increment erodent velocity: the slow erosion stage of the beginning and the stable erosion stage.

On the basis of making it clear that laterization includes such three integrated stages as weathering, micro-granularity and soil formation of laterite, the thesis illuminates characteristics of Kunming laterite in chemical composition, physical mechanics, composition of granules, fractal dimension of granularity and the connection of granules. The experiment using soil reinforced agent to solidify the laterite shows that the mechanical traits of laterite have been improved because of its involvement, the best compact indicators and shear strength ones increased and the indicators of laterites penetrability and compression decreased. The effects of reinforcement can be weighed through its coefficient and the mechanism of reinforcement can find the explanation in the effect of soil reinforced agent on the laterite granules, the changes in the electric double layer caused by soil reinforced agent and its enwrapping of laterite granules.
