摘   要：选用一种低碱度超硫酸盐水泥制备了多孔混凝土，研究了不同掺量脱硫石膏对多孔混凝土pH值和力学性能的影响，分析了狗牙根、高羊茅、早熟禾、黑麦草和白喜草在多孔混凝土中的植生情况。结果表明：当脱硫石膏掺量为15%～20%，P·O 52.5水泥掺量为5%时，多孔混凝土的抗压强度最高；水胶比为0.3时，多孔混凝土的施工性和力学性能最优；脱硫石膏、P·O 52.5水泥和水胶比对多孔混凝土的pH值影响较小。制备的多孔混凝土pH值较低，能够满足植物生长需求，其中，高羊茅和白喜草在多孔混凝土中的植生性能最佳。

Abstract: The super sulfate cement with low alkalinity was selected to prepare the eco-porous concrete, the effects of different content of desulfurization gypsum on the pH value and mechanical properties of eco-porous concrete were studied, and the planting performance of bermudagrass, tall fescue, kentucky bluegrass, ryegrass and bahia grass in eco-porous concrete was analyzed. The results show that the compressive strength of eco-porous concrete is the highest when the content of desulfurized gypsum is 15%~20% and the content of P·O 52.5 cement is 5%. When the water-binder ratio is 0.30, the workability and mechanical properties of eco-porous concrete are optimal. The content of desulfurized gypsum, P·O 52.5 cement and water-binder ratio have little influence on the pH value of eco-porous concrete. The prepared eco-porous concrete has a low pH value and can meet the needs of plant growth. Among them, tall fescue and bahia grass have the best planting performance in eco-porous concrete.

（1）珊瑚粉对水泥胶凝材料的标准稠度用水量影响不大，珊瑚粉掺量越大，凝结时间越长，水化放热量越低。
（2）当珊瑚粉掺量由0增加到30%时，胶砂强度逐渐降低，但仍能满足工程建设要求。
（3）随着珊瑚粉掺量的增加，复合胶凝材料的电阻率下降，导电性能增强；当珊瑚粉掺量为10%时，复合胶凝材料在8~18 GHz频段内的反射率低于-7 dB，可用于地面军事工程；当珊瑚粉掺量为20%和30%时，复合胶凝材料在8~18 GHz频段内的反射率均低于-5 dB，可用于民用建筑物。
（4）珊瑚粉的掺入使复合胶凝材料内部结构更加疏松多孔，且珊瑚粉不参与水泥的水化反应。
