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。
