植生混凝土试验研究及工程试用

Experimental research on green-growing concrete and its application

对植生混凝土的水胶比、目标孔隙率与抗压强度、抗折强度和实测孔隙率的关系进行试验研究,制备出孔隙率大于20%、28d抗压强度大于10 MPa的植生混凝土;并对其植物生长性能进行了工程中试,取得了一系列详实的资料。研究制备的植生混凝土及其生长基料对植物的生长有良好的适应性,生长一个月后的植物,其根系穿透了10 cm的植生混凝土层进入土体,根系的生长情况良好。

This experimental research on green-growing concrete was conducted, to clarify the relation between measured porosity, strength and water binder ratio,target porosity.The compressive strength at 28 d of the concrete with porosity above 20% reached 10 MPa, was satisfactory for slope protection and plant growing.The substrate prepared in the experiment was also available for plants to grow.One month aider grown, root of the plant passed through the concrete layer to 10 cm and grew well.
