摘要/Abstract

摘要： 植生混凝土是一种能将工程防护和生态修复很好结合起来的新型护坡材料,可实现长期持续性生态护坡。基于正交试验方法,采取低碱度硫铝酸盐水泥开展了边坡植生混凝土配合比设计,比较了混凝土水胶比、集料粒径以及富余浆量比对抗压强度、孔隙率及pH值的影响,得到最优配合比并在此基础上开展平陆运河边坡植生混凝土铺设和植物种植试验。结果表明:水胶比为0.28、集料粒径为9.5～19 mm、富余浆量比为7.75时植生混凝土各项植生性能达到最优;优选狗尾巴草、狗牙根草和宽叶草等,单独种植或混合种植时均能达到较好的效果。

Abstract: Vegetation-type concrete is a new type of slope protection material that can effectively combine engineering protection and ecological restoration, achieving long-term sustainable ecological slope protection.Based on the orthogonal experimental method, the mix proportion design of slope vegetation-type concrete was carried out using low alkalinity sulfoaluminate cement, and the effects of concrete water cement ratio, aggregate particle size, and surplus cement pastes content on compressive strength, porosity, and pH value were compared. Obtain the optimal mix proportion and conduct vegetation-type concrete laying and plant planting experiments on the slope of the Pinglu Canal based on this foundation. The results show that when the water cement ratio is 0.28, the aggregate particle size is 9.5~19 mm, and the surplus cement pastes content is 7.75, the vegetation-type concrete achieves the best vegetation performance. Choose dogtail grass, bermuda grass, and broadleaf grass for optimal results when planted alone or in combination.

Key words: vegetation-type concrete, strength, alkalinity, porosity, planting performance
