Embodiment Construction

[0036] The present invention will be further described below in conjunction with accompanying drawing.

[0037] The revetment component body is made of cement, gravel, water, water reducing agent, and plant ash, and the porosity of the revetment component body is 22%-28%, of which the water-cement ratio is 0.22-0.28, the ash-set ratio is 0.18-0.20, and the water-reducing agent It accounts for 0.2% to 0.8% of the cement consumption, plant ash accounts for 8% to 12% of the cement consumption, and the particle size of crushed stone is 19 to 26.5mm.

[0038]The cement used is ordinary Portland cement (R42.5), the crushed stone particle size is 19-26.5mm, the water-cement ratio is 0.25, the water reducing agent accounts for 0.5% of the cement consumption, and the plant ash accounts for 10% of the cement consumption. The porosity is 25%.

[0039] The preparation method of the revetment component of plant-growing porous concrete, the crushed stones are manually screened, rinsed, and...

Abstract

The invention discloses a revetment component with vegetation-form porous concrete, and a preparation method of the revetment component. The revetment component comprises a revetment component body, wherein the revetment component body is prepared from cement, macadam, water, a water reducing agent and plant ash; the porosity of the revetment component body is 22-28%; the water-cement ratio is 0.22-0.28; the cement-aggregate ratio is 0.18-0.20; the water reducing agent accounts for 0.2-0.8% of the cement content; the plant ash accounts for 8-12% of the cement content; the particle size of the macadam is 19-26.5mm. The revetment component is a vegetation-form porous concrete revetment component which is simple in raw material and matching, economic and practical, efficient and environment-friendly, and is capable of providing a growth space for green plants, small-size aquatic organisms and microorganisms, and the production method is simple and reliable.

Description

technical field [0001] The invention relates to a novel vegetation-type porous concrete bank protection component and a preparation method. The technical field belongs to the fields of river regulation, ecological concrete and environmental protection materials. [0002] The components of the invention are made of specially graded aggregates and cementitious materials, which can not only meet the requirements of various mechanical properties, but also provide a base for green plants to grow because the porous concrete has continuous voids, and the plant roots can penetrate through the concrete. The interior reaches into the soil and stabilizes the bank slope. Because green plants can grow on its surface, it not only maintains the green natural landscape, but also improves the surrounding atmospheric environment. At the same time, the uneven surface and continuous pores of porous concrete provide living space for microorganisms and small aquatic animals, maintaining biologica...
