绿化混凝土既具有混凝土护岸的稳定性和抗冲刷性能，又具有植物护岸的景观适宜性和生态功能，因而在河流护岸工程中得到广泛应用。本文研究了水灰比、水泥用量、骨料粒径、龄期等对绿化混凝土力学性能、表观密度和孔隙率的影响，发现了其中的规律性。研究表明，当采用最优水灰比时，随水泥用量增加，绿化混凝土的抗压强度、抗折强度和表观密度线性增大，孔隙率线性减小；随骨料粒级增大，绿化混凝土的抗压强度、抗折强度和孔隙率线性减小，表观密度线性增大；绿化混凝土的强度随龄期增长而增大，7d龄期抗压强度为28d龄期的0.80倍。

greening-concrete that has not only the stability and anti-erosion of concrete but also the landscape suitability and ecological function of plant revetment has been widely used in river revetment engineering. In this paper, the influence of water cement ratio, cement content, aggregate size and age on the mechanical properties, apparent density and porosity of greening-concrete have been studied. Under the conditions of optimal water cement ratio, the compressive strength, flexural strength and apparent density of greening-concrete increase linearly with the increase of the cement content; The compressive strength, flexural strength and porosity of greening-concrete decrease linearly with the increase of aggregate size; The strength of greening-concrete increase also with age.
