High-strength zeolite porous vegetation concrete and preparation method thereof
The invention discloses high-strength zeolite porous vegetation concrete and a preparation method thereof. The porous vegetation concrete is prepared from the following raw materials in parts by weight: 900-1050 parts of zeolite, 260-320 parts of cement, 4-15 parts of a reinforcing agent and 120-130 parts of water, the reinforcing agent is prepared from sodium nitrite, a polycarboxylic acid high-efficiency water reducing agent and lignosulfonate in a mass ratio of 1: (1-3): (2-5). Zeolite is used as coarse aggregate, low-alkalinity sulphoaluminate cement is used as a cementing material, and in order to improve the mechanical property of the zeolite plant-growing concrete and reduce the pH value of a pore solution, the special reinforcing agent for the plant-growing concrete is adopted to replace part of the low-alkalinity sulphoaluminate cement, so that the zeolite plant-growing concrete has good mechanical property; and the requirements of river bank protection in southern areas can be better met.
本发明公开了一种高强沸石多孔植生混凝土及其配制方法，所述多孔植生混凝土由如下重量份数的原料配制而成：沸石900‑1050份、水泥260‑320份、增强剂4‑15份和水120‑130份；所述增强剂由质量比为1:1‑3:2‑5的亚硝酸钠、聚羧酸高效减水剂和木质素磺酸盐组成。本发明以沸石为粗骨料，低碱度硫铝酸盐水泥作为胶凝材料，为提高沸石植生混凝土力学性能，降低孔隙溶液pH值，采用植生混凝土专用增强剂替代部分低碱度硫铝酸盐水泥使得沸石植生混凝土具有良好的力学性能，能够更好的满足南方地区河流护岸要求。
