摘　　要：为了探究水灰比、粉煤灰与增强剂等因素对生态混凝土强度和孔隙间碱性环境的影响,下文采用三因素三水平正交试验,分析其力学性能与植生性能,探究水灰比、粉煤灰掺量与增强剂掺量对生态混凝土抗压强度、抗折强度及孔隙碱性的影响。通过优化配比,开展植生性能试验,筛选适宜在北方寒冷地区种植的草种。结果表明:当水灰比为0.30、粉煤灰掺量为0、增强剂掺量为6%时,生态混凝土的抗压强度与抗折强度均达到最大;当各因素对应水平为水灰比0.25、粉煤灰掺量30%、增强剂掺量6%时,生态混凝土孔隙碱性最小;草种高羊茅与狗牙根在混凝土长势良好,其根茎可显著提升生态混凝土与下部土壤间的稳定性。In order to explore the effects of water-cement ratio,fly ash and reinforcing agent on the strength of ecological concrete and the pore alkaline environment.In the following paper,the mechanical properties and plant properties of the three-factor and three-level orthogonal tests were used to analyze the mechanical properties and plant properties,and the effects of water-cement ratio,fly ash content and reinforcing agent content on the compressive strength,flexural strength and pore alkalinity of ecological concrete were explored.By optimizing the ratio,the plant performance test was carried out to select the grass species suitable for planting in the cold areas of the north.The results show that when the water-cement ratio is 0.30,the fly ash content is 0,and the reinforcing agent content is 6%,the compressive strength and flexural strength of ecological concrete reach the maximum.When the corresponding levels of each factor are water-cement ratio of 0.25,fly ash content of 30%,and reinforcing agent content of 6%,the pore alkalinity of ecological concrete is the smallest.The grass species tall fescue and dogtooth root grew well in concrete,and their rhizomes could significantly improve the stability between ecological concrete and the underlying soil.
