摘要
通过大量试验,研究在一定的配合比及不同胶结材料的情况下,将植生基材填充在预制混凝土框格内,并对植被生长状况和坡面稳定性的影响作出评价,总结出凝石以及改性硫铝酸盐水泥作为胶结材料能更好地满足植物生长的要求。在基材中使用1.5%的粘结剂——改性醋酸乙烯乳液,不仅能使抗冲刷性达到要求,而且对多孔混凝土结构也能起到稳定作用。
Through a great deal of tests,the growth condition of vegetation and slope stability while vegetation substrate is filled into fabricated concrete with a certain mix proportion and different cementing materials are evaluated.It is concluded that condensate stone and modified sulphate aluminate cement,as a cementing material,can meet the requirements of plant growth better.Using 1.5% binder—modified vinyl acetate emulsion in substrate can not only make the scour resistance of slope meet standard,but also stabilize the porous concrete structure.
