Performance of Vegetation-Type Concrete Based on Orthogonal Experimental Method

Abstract

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
