Abstract

The invention discloses a magnesium phosphate cement foamed concrete sand stabilizing plate and a preparation method thereof. A magnesium phosphate cement base material is prepared from soluble phosphate, retarded adhesive material, magnesium oxide, fine sand, water and inorganic foaming agent or foam prepared by plant foaming agent. A preparation method of the magnesium phosphate cement foamed concrete sand stabilizing plate is prepared by preparing soluble phosphate, retarded adhesive material, magnesium oxide, fine sand at ratio, fully mixing the components, adding water to mix evenly; filling the foam prepared by the animal plant foaming agent or inorganic foaming agent, and stirring evenly; placing to a plate-shaped module and maintaining; after the slurry is completely set, demoulding and preparing the magnesium phosphate cement foamed concrete sand stabilizing plate. The magnesium phosphate cement foamed concrete sand stabilizing plate is low in material cost, green and environment-friendly, stable in physical performance, strong in weather-proof ability, simple in construction and installation, and wide in application prospect in desertification control project.

Description

technical field [0001] The invention belongs to the technical field of desertification control, and in particular relates to a magnesium phosphate cement foam concrete sand-fixing board and a preparation method thereof. Background technique [0002] my country is one of the countries with serious desertification hazards in the world. As an important national policy, desertification control has been highly valued. The key to desertification control is sand prevention and sand fixation. At present, the main methods of desert control at home and abroad are physical sand fixation (such as stone squares, earth squares) and biological sand fixation (such as planting plants). Several common sand-fixing methods such as: Grass grid sand barrier is a grid-shaped windshield wall made of wheat straw, straw, reed and other materials on the mobile sand dunes to weaken the erosion of wind. Although the grass grid sand barrier is low in cost and simple in construction, it has high efficie...
