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。
The ecological grass-planting concrete is a type of porous pervious concrete which can be suitable for the growth of herbs. In this paper, the influence of the composition of the porous concrete on the grass-planting performance and the growth of different grass species in porous concrete are studied. The results show that the use of concrete with relatively large particle size and relatively concentrated aggregates helps to improve the porosity and the size and connectivity of the pores. Replacing some of the cement with mineral admixtures is beneficial for reducing the pH value and replacing it with recycled aggregates Natural aggregates help improve the water retention capacity of concrete, which is good for the growth of grass in porous concrete. Peaks and belligerents two grass species more suitable for growth in porous concrete.
