阐述了普通水泥土受冻融破坏机理,介绍了植被混凝土基材与普通水泥土的差异,旨在改进植被混凝土基材抗冻性能。结合普通水泥土抗冻性能研究成果,提出了以植物纤维、玻璃纤维、超细矿粉和引气剂作为外掺料改进基材抗冻性能的措施,并通过直剪试验阐述了植物纤维对基材力学性能的增强作用。最后,说明了应用上述措施时需要解决的掺料的配比确定、植物纤维的类型选取和施工喷播技术的改进等。
The mechanism of ordinary cement soil freezing and thawing damage is expounded. The difference between vegetation concrete substrate and ordinary cement soil is introduced to improve the frost resistance of vegetation concrete substrate. Combined with the research results on the frost resistance of ordinary cement soil, the measures to improve the frost resistance of the substrate by using plant fiber, glass fiber, ultrafine slag powder and air entraining agent as external admixture were proposed. And the plant fiber pairs Enhance the mechanical properties of the substrate. Finally, the application of the above measures to determine the need to address the need to resolve the ratio of spice, plant fiber type selection and construction of spray technology improvements.
