摘　　要：保水材料是植被混凝土重要的组成部分,研究了不同保水材料对植被混凝土团聚特性的影响。结果显示,聚丙烯酸盐型类保水材料具有最高的吸水倍数,而聚丙烯酸/无机矿物型保水材料展现出最佳的保水能力。保水材料的加入显著影响了植被混凝土的团聚体分布,主要集中在2~5 mm范围内,有助于提升其结构稳定性。保水材料的持水能力与植被混凝土团聚粒径范围呈线性关系,表明持水能力强的保水材料能有效促进中等粒径、稳定性团聚体的形成,从而增强植被混凝土的团聚特性。Water retention materials are an important component of vegetated concrete.This study investigates the influence of different water retention materials on the aggregation characteristics of vegetated concrete.The results indicate that polyacrylate-type water retention materials have the highest water absorption capacity,while polyacrylic acid/inorganic mineral-type water retention materials exhibit the best water retention capability.The addition of water retention materials significantly affects the aggregate distribution of vegetated concrete,primarily concentrating in the 2~5 mm range,which helps improve its structural stability.There is a linear relationship between the water retention capacity of the water retention material and the aggregate particle size range of the vegetated concrete.This suggests that water retention materials with strong water-holding capacity can effectively promote the formation of large-sized,stable aggregates,thereby enhancing the aggregation characteristics of vegetated concrete.
