A kind of ecological concrete for slope greening and preparation method thereof

Abstract

The invention discloses slope-greening eco-concrete and a preparation method thereof and relates to the slope-greening field. The slope-greening eco-concrete comprises the following ingredients: 1200-1300 parts of coarse sand, 200-250 parts of pottery sand, 70-100 parts of cement, 25-50 parts of sodium carboxymethylcellulose, 20-30 parts of sodium silicate, 3-5 parts of calcium superphosphate, 2-3 parts of vermiculite, 2-3 parts of perlite, 5-10 parts of turfy soil and 160-200 parts of water. The preparation method comprises the following steps: preparing the raw materials; throwing coarse sand, pottery sand, cement, vermiculite and perlite into a first blender to be blended; throwing sodium carboxymethylcellulose, calcium superphosphate and water into a second blender to be blended; throwing the material in the second blender into a first blender to be blended; throwing turfy soil into the first blender to be blended to obtain the slope-greening eco-concrete. The slope-greening eco-concrete is strong in adhesion, high in strength, low in cement consumption and suitable for plant survival.

Description

technical field [0001] The invention relates to the field of slope greening, in particular to an ecological concrete used for slope greening and a preparation method thereof. Background technique [0002] Side slope refers to the slope with a certain slope made on both sides of the roadbed to ensure the stability of the roadbed. With the continuous increase of construction projects such as highways, railways, and urban construction projects in our country, the phenomenon of vegetation destruction has become increasingly serious, forming many exposed slopes, which have a negative impact on the ecological environment. The traditional slope greening method is to use foreign soil spraying technology. The foreign soil spraying is to make the foreign soil form a granulated structure with agglomerates, and the reinforcing fibers play a role in reinforcing the network similar to plant rhizomes, thus creating a certain Thickness is resistant to rainwater and wind erosion, firm and b...

Problems solved by technology

The traditional slope greening method is to use foreign soil spraying technology. The foreign soil spraying is to make the foreign soil form a granulated structure with agglomerates, and the reinforcing fibers play a role in reinforcing the network similar to plant rhizomes, thus creating a certain Thickness is resistant to rainwater and wind erosion, firm and breathable, with a porous and stable soil structure similar to or better than natural topsoil, and then sprayed with plant seeds to achieve the purpose of slope greening, but the foreign soil has low adhesion and low strength , prone to landslides in rainy weather

In order to overcome the above defects, some ecological concretes with high adhesion and high strength have emerged one after another to replace foreign soil for slope greening. However, the amount of cement in these ecological concretes is relatively large, which is not suitable for plant survival.
