Abstract
The invention provides an environment-friendly aerated concrete block which at least comprises, by weight, 70%-82% of stone tailings and/or coal ash, 4%-10% of cement, 12%-19% of quicklime, 0.05-0.08% of powdered aluminum and 0.9%-2.7% of desulfurization gypsum. The environment-friendly aerated concrete block uses the stone tailings as a raw material, so that production cost is reduced, and the problem of difficulty in treatment of the stone tailings is further solved.
Description
Technical field
The present invention relates to a kind of concrete segment, be specifically related to the air-entrained concrete building block that a kind of light porous, heat insulating, fire resistance are good, can follow closely, can saw, can dig and have certain shock resistance, belong to building material field.
Background technology
Concrete is widely used in the building field, available coagulation soil be by gelling material and water according to certain mixed proportioning after, the artificial stone-like material that sclerosis forms with certain intensity.Along with present people's life requirement improves constantly, also increasingly high to the requirement of material of construction, available coagulation soil more and more can not satisfy the growing material life demand of people.Novel wall materials such as existing on the market at present all kinds of holllow building blocks, light wall board, but factors such as technology own, equipment all be limited to, exist all drawbacks.
Air-entrained concrete building block is the New Building Materials of a kind of less energy-consumption, environment-friendly type, have in light weight, thermal and insulating performance good, intensity is high, anti-seismic performance is good, good processability, high temperature resistant, advantage such as sound-proofing properties is good.Thereby the universal traditional concrete that replaces gradually.But because the production cost of air-entrained concrete building block is higher, thereby limited its development.
Lithotome such as marble, grouan is because the meliority of its performance and outward appearance is favored by people just more and more, along with increasing of its marketable value, also comes more popular to the exploitation of this type ore.Along with exploitation without restraint to these stone materials; Brought the destruction of a lot of environmental protection aspect thereupon; The stone material tailings (chip, powder, dust and mud etc.) that carries over after the stone material cutting can't be handled, and directly abandons accumulation usually, serious especially destruction ecotope.
Summary of the invention
The invention provides a kind of environment-friendly type air-entrained concrete building block, solved the deficiency in the above-mentioned background technology, the stone material tailings as the raw material of producing air-entrained concrete building block, has not only been reduced production cost, also solved a difficult problem of handling the stone material tailings simultaneously.
Realize that the technical scheme that above-mentioned purpose of the present invention adopted is:
A kind of environmental protection air-entrained concrete building block; The raw material of described air-entrained concrete building block comprises stone material tailings and/or flyash, cement, unslaked lime, aluminium powder and desulfurated plaster at least; The per-cent that each raw material accounts for the raw material gross weight is respectively stone material tailings and/or flyash 70%-82%, cement 4%-10%, unslaked lime 12%-19%; Aluminium powder 0.05%-0.08%, desulfurated plaster 0.9%-2.7%.
