摘　　要：选用低碱水泥、矿物掺合料制备植生混凝土,研究骨料类型、级配、孔隙率、矿物掺合料对植生混凝土拌合物性能、物理力学性能、pH值的影响,得出如下结论:用低碱水泥、矿物掺合料制备植生混凝土,胶浆流动度在200~230 mm之间,植生混凝土抗压强度达6.0~9.0 MPa,孔溶液pH值降低至10.2~11.5。低碱植生混凝土在提高孔隙率、降低pH值及提高植物的适生性能等方面具有明显效果。Planting concrete was prepared with low-alkali cement and mineral admixtures to study the effects of aggregate type,grading,porosity and mineral admixtures on the mixture performance,physical and mechanical properties,pH value of planting concrete.It is concluded that the planting concrete prepared with low-alkali cement and mineral admixtures has a mortar fluidity of 200~230mm,a compressive strength of 6.0~9.0MPa,and the pH value of the pore solution variable within 10.2~11.5.Low-alkali planting concrete has significant effects in increasing porosity,reducing pH value,and improving plant adaptability.
