Abstract

The invention provides a nitrogen fertilizer slow-release vegetation cementing material. The nitrogen fertilizer slow-release vegetation cementing material is prepared from the following components in parts by weight: 45 to 70 parts of cement clinker, 6 to 10 parts of gypsum, 10 to 25 parts of high-permeability volcanic ash, 5 to 20 parts of kaolin, 1.5 to 3 parts of water-absorbent resin and 2 to 8 parts of nitrogen fertilizer. The nitrogen fertilizer slow-release vegetation cementing material has the advantages that by containing the high-permeability volcanic ash, the kaolin and the water-absorbent resin, the high-permeability volcanic ash is a kind of natural volcanic ash mineral with higher permeability, and the slow-release property of a nitrogen fertilizer is good; the kaolin is a kind of clay and clay rock using kaolin family clay minerals as a main material, and is a 1:1 type laminar silicate, and the good slow-release property on the nitrogen fertilizer is realized by a special laminar structure of the kaolin; by utilizing the kaolin, the high-permeability volcanic ash and the water-absorbent resin, the slow-release property of the nitrogen fertilizer is greatly improved, the slow-release period is 6 to 8 months, the requirement of growth cycle of plants is met, and the problem of failure to realize the edge slope greening and improve the ecological environment by vegetation concrete, caused by early death of the plants due to unenough nitrogen fertilizer is solved.

Description

technical field [0001] The invention relates to the technical field of environmental protection building materials, in particular to a nitrogen fertilizer slow-release plant growth gelling material and a preparation method thereof. Background technique [0002] Ordinary concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate, and water (with or without admixtures and admixtures) in a certain proportion, after mixing, molding and curing. It is used to bear loads and is widely used in the fields of national infrastructure construction and civil engineering. Plant-grown cement concrete is a cement concrete with a porous and macroporous structure that is formed by wrapping a layer of cement slurry on the surface of coarse aggregates with similar particle sizes. Compared with ordinary concrete, plant-grown cement concrete can not only protect slopes and prevent soil erosion, but also has good air permeability ...
