The invention discloses an environmentally-friendly hollow
brick used for buildings. The environmentally-friendly hollow
brick is prepared from the following raw materials in parts by weight: 15-25 parts of
cement, 25-35 parts of ore
tailings, 15-20 parts of purified filler, 3-5 parts of
plant powder, 2-4 parts of sulphur
powder, 0.5-1.5 parts of nano-
zinc oxide, 2-4 parts of
glass fiber, 1-2 parts of carbon
fiber, 30-40 parts of
coal ash, 10-16 parts of
emulsion powder and 6-8 parts of industrial
mildew preventive. The environmentally-friendly hollow
brick used for building decoration has the characteristics of abrasion resistance, high
compressive strength, high water absorption,
fire prevention and temperature preservation. In addition, the environmentally-friendly hollow brick also has functions of emitting aromatic
odor and purifying air, a great quantity of industrial wastes are used as raw materials so as to perform effects on saving energy, reducing emission, preventing environment
pollution and being ecological and
environmentally friendly. Meanwhile, the preparation method for the hollow brick has the advantages of lower material cost, abundant
raw material, simple and clear technology, easiness in operation, easiness in realizing industrial production, higher practical value and good application prospect.
