High-strength wear-resisting water permeable brick

Abstract

The invention mainly relates to the technical field of buildings, and discloses a high-strength wear-resisting water permeable brick. The high-strength wear-resisting water permeable brick is preparedby the following raw materials: 64-66 parts of casting used sand, 37-39 parts of waste ceramic, 23-25 parts of volcanics, 15-17 parts of zeolite powder, 6-8 parts of sepiolite powder, 5-7 parts of cement, and 4-6 parts of modified yellow cement gum. The provided high-strength wear-resisting water permeable brick is extensive in raw material source, low in price, simple in preparation process, high in strength, strong in abrasive resistance, and capable of avoiding the surface of the water permeable brick from generating damaging and slag-falling phenomena, and apparently prolonging service life. Waste ceramic is smashed, and added to hydrochloric acid solution for soaking, and high-temperature heating is performed, a porous structure of the waste ceramic is increased, and water permeability and water-retaining property of the water permeable brick are improved. Smashed volcanic particles are larger, integrity of the porous structure thereof can be kept, and abrasion resistance of thewater permeable brick can be improved, a smashing phenomenon is avoided from being generated after the water permeable brick is used for a period of time.

Description

technical field [0001] The invention mainly relates to the technical field of construction, in particular to a high-strength wear-resistant permeable brick. Background technique [0002] Permeable bricks are widely used in the reconstruction of urban roads. They are generally formed by pressing. There are many pores inside the brick body, which can seep water quickly and achieve the effect of anti-skid, which plays a certain role in guaranteeing the safety of citizens; but currently on the market Many permeable bricks sold have good water permeability and anti-skid effects, but their strength is low and they are not wear-resistant. After a period of use, surface damage and slag will appear, which will have a certain impact on the environment. [0003] The existing patent document CN 108285316 A discloses a high-strength permeable brick, and specifically discloses that the porogen includes by weight: 4-8 parts of paper mill sludge, 2-6 parts of sepiolite powder; the toughenin...

[0002] Permeable bricks are widely used in the reconstruction of urban roads. They are generally formed by pressing. There are many pores inside the brick body, which can seep water quickly and achieve the effect of anti-skid, which plays a certain role in guaranteeing the safety of citizens; but currently on the market Many permeable bricks sold have good water permeability and anti-slip effects, but their strength is low and they are not wear-resistant. After a period of use, surface damage and slag will appear, which will have a certain impact on the environment.

[0003] The existing patent document CN 108285316 A discloses a high-strength permeable brick, and specifically discloses that the porogen includes by weight: 4-8 parts of paper mill sludge, 2-6 parts of sepiolite powder; the toughening compound is as follows Process preparation: Stir wool fiber, acrylate grafted styrene, urea, triethanolamine, and water, soak under high pressure, filter, wash, and blow dry to obtain a toughened compound; add paper mill sludge and wool fiber to the raw materials, Paper mill sludge is rich in microorganisms. Wool fiber is a natural protein fiber whose main component is protein called keratin. Long-term contact will cause the wool fiber to decompose and the structure of the brick body will change. Therefore, just after the preparation is completed The strength of the permeable brick is relatively high, but the strength will decrease significantly after a period of time, which will reduce the performance of the permeable brick and cannot meet the requirements of water permeability and high strength.
