Problems solved by technology

Cement permeable bricks either have low water permeability or good water permeability, but the compressive strength is not high. It is difficult to balance the performance of these two aspects; the cost of using polymer binders and manual processing of sand permeable bricks is high and cannot be widely promoted

Abstract

The invention discloses a novel water permeable material using desert sand as aggregate, and a preparation method and application of the novel water permeable material. The material is characterized by comprising the following ingredients in parts by weight: 70-95 parts of desert sand, 1-10 parts of aqueous polymer binder, 2-10 parts of inorganic binder and 0-3 parts of colorant. The preparation method of the novel water permeable material comprises the following steps of uniformly stirring the desert sand, the inorganic binder, the colorant and the aqueous polymer binder, filling into a mold and using a pressurizing band vibration molding process to prepare water permeable road bricks and water permeable plates. According to the invention, the raw desert sand is utilized, so that the waste is changed into wealth; compared with a resin type water permeable brick, the material is low in price and good in water permeability; environment-friendly binders which are free of toxin, smell and pollution are utilized; the material is wide in application field; when being used for preparing water permeable bricks which are paved on sidewalks and roads in parks, residential areas and the like, the material is beneficial for underground water circulation.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a novel water-permeable material using desert sand as an aggregate, a preparation method and application thereof. Background technique [0002] At present, due to the needs of the development of the urban ecological environment, the urban ground is gradually being covered by impermeable materials such as cement and asphalt to be covered by permeable pavement materials. The traditional method is composed of large particle skeleton and cement or artificially processed sand and polymer binder. Cement permeable bricks either have low water permeability or good water permeability but low compressive strength. It is difficult to balance the performance of these two aspects; the cost of using polymer binders and manual processing of sand permeable bricks is high and cannot be widely promoted. Desert sand is currently a waste that is difficult to use with high added value. ...
