Embodiment 1

[0022] A planting concrete for ecological slope protection, made of the following raw materials in parts by weight: 10 parts of pottery sand, 15 parts of pumice, 120 parts of cement, 22 parts of perlite, 2 parts of sodium bicarbonate, 20 parts of biomass fiber, rheological 1 part of additive, 20 parts of admixture, and 75 parts of water; wherein, the admixture is made of the following raw materials in parts by weight: 30 parts of polylactic acid, 8 parts of butyl methacrylate, 1.5 parts of acrylic acid, and 2 parts of emulsifier , 0.2 parts of dodecyl mercaptan.

[0023] The preparation method of the planting concrete for above-mentioned ecological slope protection comprises the following steps:

[0024] (1) Weighing each raw material by parts by weight, crushing and sieving pottery sand, pumice and perlite respectively;

[0025] (2) Take part of the water, add sodium bicarbonate, and disperse evenly to obtain preparation A; take the remaining water, add biomass fiber, and ob...

Abstract

The invention discloses vegetation concrete for ecological slope protection. The vegetation concrete is prepared from the following raw materials in parts by weight: 8-12 parts of pottery sand, 13-17parts of pumice, 100-150 parts of cement, 20-25 parts of perlite, 1.5-2.5 parts of sodium bicarbonate, 15-25 parts of biomass fibers, 0.5-2 parts of a rheological agent, 18-27 parts of an admixture and 60-90 parts of water, wherein the admixture is prepared from polylactic acid, butyl methacrylate, acrylic acid, an emulsifier and a polymerization regulator. The invention also discloses a preparation method of the vegetation concrete. The prepared vegetation concrete takes a porous structure as a basic carrier, is uniform in pore, good in water-retaining property and water permeability and highin compressive strength, has a certain soil fixing effect, and can realize the functions of vegetation greening, biological coexistence, water quality purification and the like.

Description

technical field [0001] The invention belongs to the technical field of ecological slope protection, and in particular relates to a planting concrete for ecological slope protection and a preparation method thereof. Background technique [0002] With the development of urbanization, people have gradually discovered that traditional concrete not only has a negative impact on the living environment of people in the process of urban construction, but also affects the ecological characteristics of nature. The texture of traditional concrete is brittle and hard, strong alkaline, and rough surface, which is not conducive to the growth of green plants. Its structures give people a hard, cold, gray and lifeless impression, lack of artistic beauty, and disturb the relationship between human and natural ecology. harmonious relationship. Ecological concrete is a theory based on the combination of concrete and ecological concepts. It was first proposed by Japanese scholars. The purpose ...
