透水生态混凝土与植草性能的研究

生态植草混凝土是一类能够适宜草本植物生长的多孔透水混凝土,本文就多孔混凝土的组成对植草性能的影响以及不同草种在多孔混凝土中的生长情况进行了研究.研究结果表明:利用粒径比较大、比较集中的集料制备的混凝土有利于提高空隙率和孔隙的尺寸及连通程度,用矿物掺合料代替部分水泥有利于降低pH值,用再生集料代替天然集料有利于提高混凝土保水能力,这些都有利于草在多孔混凝土中的生长.顶峰和交战两个草种比较适合在多孔混凝土中生长.

Investigation on Porous Eco-Concrete and Its Planting Performance

The porous eco-concrete is a kind of pervious concrete in which the plants can grow,in this paper the influence of the concrete compositions on the planting grass performance of the porous concrete and the growing status of the different kinds of grass in the porous concrete are studied.The result indicates that the aggregate with big size can form higher void ratio and better connect pores than others,the replacement of mineral mixture to the cement decrease the pH value of the soil in the void,and the recycling aggregate can improve the water retaining capability of the porous concrete,they all contribute to the planting performance of the concrete,the grass sort Pinnacle and Crossfire are very suitable to be seeded in the porous concrete.
