【摘要】：多孔生态混凝土物理力学性能受配合比因素影响,为找出对应影响规律,本文制备不同水胶比、不同目标孔隙率的多孔生态混凝土,测试其物理力学性能。利用制备的多孔混凝土,设计试种试验,从6组草种中筛选出适宜多孔生态混凝土建植使用的草种。结果证明,多孔生态混凝土早期强度低,目标孔隙率越高,密实程度越低的多孔生态混凝土,成型后抗压强度越低,且其强度受水胶比影响更小。水胶比越高,制备的多孔生态混凝土实测孔隙率越高。试验所用草种中除狗牙根、紫羊茅与细弱剪股颖三种草种不适应多孔生态混凝土生长环境,其他草种均表现出良好适应性,其中,高羊茅最适宜作为多孔生态混凝土建植草种。
[Abstract]:The physical and mechanical properties of porous ecological concrete are affected by mixing ratio. In order to find out the corresponding law, porous ecological concrete with different water / binder ratio and different target porosity is prepared and its physical and mechanical properties are tested. By using the porous concrete prepared in this paper, the suitable grass species for the establishment and planting of porous ecological concrete were selected from 6 groups of grass species. The results show that the low early strength of porous ecological concrete, the higher the porosity of the target and the lower the density of the porous ecological concrete, the lower the compressive strength after forming, and the less the influence of water-binder ratio on the strength of the porous ecological concrete. The higher the water-binder ratio, the higher the measured porosity of the prepared porous ecological concrete. The three species of grass in the experiment, except dogtooth, purple fescue and thin shearing glume, could not adapt to the growth environment of porous ecological concrete, and other grass species showed good adaptability, among which tall fescue was the most suitable for planting grass species as porous ecological concrete.
