多孔混凝土植被砖的立体绿化应用
Application of Porous Concrete Brick in Vertical Greening
摘要
Abstract
Based on the environmental characteristics of stereo greening,the utility model of porous concrete brick which suitable for the construction of the three-dimensional greening wall surface and the roof greening construction was expected to be developed,while the plants with strong resistance were screened.The results showed that the physical and chemical properties of cement can affect the growth of plants,and when the water cement ratio is 0.25,the ash collection ratio is 3:1,and the crushed stone is used as coarse aggregate,the porous concrete with effective porosity of more than 20% and high compressive strength and flexural strength can be obtained.It is found that the compressive strength and flexural strength of porous concrete are inversely proportional to the aggregate size,and the compressive strength and flexural strength of porous concrete decrease with the increase of aggregate size.The planting test found that sarmentosum and sedum lineare grew better in vegetation brick,with high coverage and strong resistance.The porous concrete brick has been successfully applied in the three-dimensional greening,which has the characteristics of fast and low cost,and is easy to be popularized.关键词
