摘 要:研究了不同成型方式和水灰比对植生混凝土性能的影响。结果表明:振动成型的植生混凝土的连续孔隙率最小,插捣成型的植生混凝土的抗压强度最高,压捣成型的植生混凝土的连续孔隙率和抗压强度均满足相关设计要求;植生混凝土的抗压强度随着水灰比的增大而降低,连续孔隙率随着水灰比的增大而增大;当水灰比为0.27时,采用压捣成型方式制备得到的植生混凝土的性能满足相关设计要求,并已成功应用于济南赵庄险工48#坝坝坡防护工程。
Abstract: The effects of different forming methods and water-cement ratio on the properties of planting concrete were studied. The results show that the porosity of the planting concrete based on vibration molding is the smallest, the compressive strength of the planting concrete based on plug tamping is the highest, and the porosity and compressive strength of the planting concrete based on pressure tamping meet the relevant design requirements. The compressive strength of planting concrete decreases with the increase of water-cement ratio, and the porosity increases with the increase of water-cement ratio. When the water-cement ratio is 0.27, the performance of planting concrete prepared by pressure tamping method meets the relevant design requirements, and has been successfully applied to the dam slope protection project of Zhaozhuang dangerous engineering 48# dam in Jinan.
