Embodiment 1

[0020] A. Preparation of porous concrete: Mix stones, cement, soil, polycarboxylate superplasticizer, polymer emulsion, organic fertilizer, concrete alkaline conditioner, and water with a particle size of 10mm to 15mm and add them to the mixer according to the following ratio Stir to form. Among them, the ratio of each component is: stone 1633kg / m 3 , cement 230kg / m 3 , soil 120kg / m 3 , organic fertilizer 8kg / m 3 , Polycarboxylate superplasticizer 2.3kg / m 3 , polymer emulsion 57.5kg / m 3 , Concrete alkaline conditioner 2.3kg / m 3 %, water-cement ratio 0.35.

[0021] B. Preparation of mixed soil: Soak the grass seeds in tap water for 8-10 hours, and then mix them evenly with the soil in a weight ratio of 1:2-3 to obtain a mixed soil.

[0022] C, preparation of vegetation-type porous concrete: the mixed soil obtained in step B is covered on the porous concrete surface layer obtained in step A, wherein the thickness of the porous concrete is 50mm, and the thickness of the mi...

Abstract

The invention discloses vegetation form cellular concrete and a method for preparing the same. The method comprises the following steps: A, adding carpolites, cement, soil, a polycarboxylate water reducing agent, a polymer emulsion, an organic fertilizer, a concrete alkaline modifier and water into a stirrer according to the stated proportion, and stirring and forming the mixture to obtain the cellular concrete; B, soaking grass seeds with tap water for 8 to 10 hours, and mixing the grass seeds with the soil evenly according to the weight ratio of 1:2-3 to obtain mixed soil; and C, covering the surface layer of the formed cellular concrete obtained in the step A with the mixed soil obtained in the step B to prepare the vegetation form cellular concrete. The vegetation form cellular concrete and the method are applicable to upstream face vegetation bank protection of a dike, roadbed slope protection of a highway, and the like, a green parking area, and the like. The vegetation form cellular concrete can increase green spaces in cities, absorb noises and dust, and play a positive role in keeping the ecological balance of city climate.

Description

technical field [0001] The invention relates to the field of civil engineering materials, in particular to a plant-type porous concrete. [0002] The present invention also relates to a preparation method of the plant-growing porous concrete. Background technique [0003] Vegetation concrete can increase the green space of the city, absorb noise and dust, and play a positive role in the ecological balance of the urban climate. At the same time, it can also be used for embankment revetment, roadbed slope protection for expressways, green parking lots, etc. [0004] At present, the preparation of vegetation concrete generally adopts the method of planting grass in porous concrete, but because porous concrete generally has low tensile strength, high brittleness, and is easy to crack, and because the concrete is too alkaline, the growth of plants is not good. Contents of the invention [0005] The technical problem to be solved by the present invention is to overcome the abov...
