摘要
针对华北地区独特的地理、地形和气候条件,对生态混凝土进行抗压强度试验,分析植物根系在生态混凝土中的生长情况及植物气孔分布情况,对生态混凝土在华北地区的应用进行初步研究。研究结果表明,胶结材料的组成不仅决定着生态混凝土的配合比,还影响生态混凝土强度和孔隙特性;根系通过利用混凝土孔隙中的少量营养物质穿过生态混凝土,对混凝土孔径具有适应性;生长在生态混凝土上的麦冬气孔密度明显高于生长在对照试验组上的麦冬。
Based on the unique geographical topography and climatic conditions of North China,the compressive strength test of ecological concrete was carried out to analyze the growth of plant roots in ecological concrete and the distribution of plant stomata.The application of ecological concrete in North China was explored.The results show that the composition of the cemented material not only determines the mix ratio of the ecological concrete,but also affects its strength and stomatal characteristics.The roots pass through the concrete through a small number of concrete stomata,and are adaptable to the ecological concrete stomatal size.The stomatal density of Ophiopogon japonicus grown on ecological concrete was significantly higher than that of the stomatal growth test group.
