Abstract

A magnesium oxysulfate cement foam concrete sand stabilizing plate and a preparing method thereof are disclosed. The plate includes magnesium sulfate (MgSO4), magnesium oxide, fine sand, water and foam generated by an inorganic foaming agent or a plant foaming agent. The method includes weighing the magnesium oxide and the fine sand according to a weight ratio of 1:(1-30); fully mixing the magnesium oxide and the fine sand; fully stirring and mixing the material mixture and a magnesium sulfate solution according to a ratio; adding the foam generated by the inorganic foaming agent or the plant foaming agent into the mixture; fully stirring the mixture; feeding the obtained mixture to a plate-type mold; curing the mixture; and demolding after the mixture slurry is completely cured to obtain the plate. According to the plate, raw materials are easily available, a production process is simple, a cost is low, sand-preventing and sand stabilizing effects are good, and the plate has good popularization value and application value.

Description

technical field [0001] The invention belongs to the technical field of desertification control, and in particular relates to a magnesium oxysulfide 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 effici...
