Study on Planting Performance and Scouring Resistance of Eco-Concrete

Abstract

Abstract: Through designing eco-concrete planting tests and scouring tests containing three slope conditions, four slope gradients, and three rainfall intensities, the planting performance of eco-concrete and its scouring resistance after combining with plants were studied. The planting test results show that at 20 d of planting, the plant height of eco-concrete planting group is up to 22.5 cm, the plant spotting index is 95.37% and the plant coverage is 102.6%. The plant stem and leaf growth conditions of the eco-concrete planting group and plain soil planting group are not significantly different, but the plant root in plain soil planting group is generally longer. At 40 d of planting, the root distribution of the two groups is close in extent. The scouring test results show that soil loss in plain soil slope and eco-concrete cladding slope can produce a surge with the increase of rainfall accumulation under specific conditions, while soil loss from eco-concrete planting slope does not surge under all experimental conditions. The scouring resistance under the same scouring condition is eco-concrete planting slope > eco-concrete cladding slope > plain soil slope.

Key words: eco-concrete, slope protection, planting performance, slope erosion, soil loss, scouring resistance
