Problems solved by technology

However, the cement hardened slurry has low water absorption rate and poor water retention performance. Therefore, the vegetable cement concrete prepared with ordinary cement cannot meet the water demand of plant growth, and will cause plants to dry up and die due to insufficient water, resulting in vegetable cement concrete. Slope, the role of improving the ecological environment
Therefore, the popularization and application of vegetable cement concrete is severely restricted.

Abstract

The invention belongs to the technical field of environment-friendly building materials, and relates to a plant-growth cement-base material, particularly an organic-inorganic composite water-retaining plant-growth cement-base material. The organic-inorganic composite water-retaining plant-growth cement-base material is composed of the following raw materials in parts by weight: 50-70 parts of sulfoaluminate cement, 1-5 parts of methyl cellulose, 1-10 parts of high-water-absorptivity resin, 5-25 parts of vermiculite and 5-25 parts of diatomite. The organic-inorganic composite water-retaining plant-growth cement-base material has the advantages of accessible raw materials, low cost and excellent water retention property, and can satisfy the demands of plant growth for water content, thereby performing the functions of greening and ecological environment improvement.

Description

technical field [0001] The invention belongs to the technical field of environment-friendly building materials, in particular to a vegetable cement-based material, in particular to an organic-inorganic composite water-retaining vegetable cement-based material. Background technique [0002] Traditional cement and its concrete have been widely used in the fields of national infrastructure construction and civil engineering because of their high strength and high hardness. Its function is mainly used to bear the load, which belongs to the structural material. However, many infrastructure construction projects, such as slope protection projects such as road slopes, river embankments, tunnel entrances, barren hills and steep slopes, not only require cement and its concrete to have a certain mechanical strength, but also require it to have a certain greening slope and improve the ecological environment. function of the environment. Vegetated cement concrete with porous and macro...
