摘　　要：以提高植被混凝土的抗冻性能为核心,在保证透水性能的前提下,采用粗纤维(塑钢纤维)、细纤维(聚丙烯腈纤维)、建筑胶粉和砂复合增强的方法,同时掺加适量引气剂等材料提高植被混凝土的抗冻性能。通过正交试验,初步确定了新型抗冻植被混凝土的最佳配比,按此配比成型的植被混凝土抗冻等级大幅提高到F150,其力学性能和透水性能也得到了较大改善,该植被混凝土可在北方寒冷地区推广应用。In order to improve the frost resistance of vegetation concrete as the core,under the premise of ensuring the perme- ability,the crude fiber（steel fiber）,fine fiber（polypropylene fiber）,building glue and sand composite enhancement method,also with an appropriate amount of air entraining agent and other materials improving the frost resistance of concrete. Through orthogonal testiinitially identified the best ratio of new antifreeze vegetation concrete,used the ratio of forming the vegetation concrete frost resistance grade greatly increased to F150,the mechanical properties and permeability have also been greatly improved,all above have laid the foundation for vegetation concrete application in the northern cold area.
