摘　　要：聚合物骨架空隙混凝土是用聚合物水泥结合料固结骨料形成的骨架+节点+空隙的内部空间网架结构混凝土,在道路路面结构中应用具有透水、降噪等优点。根据规范进行了干缩性试验,对聚合物骨架空隙混凝土和普通水泥混凝土、无砂多孔混凝土的干缩性能进行了对比,得到聚合物骨架空隙混凝土不同龄期的干缩率,表明聚合物骨架空隙混凝土具有良好的干缩性能。The pavement which is made of polymer lattice porous concrete is a new kind of road surface structure, and it has many advantages in engineering practice, such as water permeability, noise-decreasing and color landscape features. Polymer lattice porous concrete is the internal space frame structure with frames, nodes and interspaces that have been consolidated by polymer cement. According to related specifications, the test of drying shrinkage performance is carried out. The drying shrinkage performance of polymer lattice porous concrete is compared with that of general cement concrete and large porous concrete without sand. The drying shrinkage ratios of polymer lattice porous concrete at different ages are obtained. The results show that polymer lattice porous concrete has favorable drying shrinkage performance.
