Abstract
The invention provides a waste marble powder autoclaved aerated concrete block. A main component is waste marble powder containing unsaturated polyester resin. The waste marble powder is produced during a marble material surface polishing process. The aerated concrete comprises the components of, in percentages by mass, 55-68% of waste marble powder, 6-8% of cement, 2-5% of desulfurization gypsum, 25-32% of lime, and 0.08% of aluminum powder. The content of the unsaturated polyester resin in the waste marble powder is 1-2%. Because the waste marble powder contains the unsaturated polyester resin, an effect of an adhesive can be provided. Therefore, the prepared aerated concrete block has the characteristics of light weight, high strength and good thermal insulation performance. The concrete block is an energy-saving building material. Also, the application field of the waste marble powder is expanded; the added value of the waste marble powder is improved; and a novel approach is provided for the reutilization of waste rock powder.
Description
Technical field
The invention belongs to environmental-friendly construction material field, relate to a kind of waste marble powder autoclave aerated concrete building block.
Background technology
Tradition autoclave aerated concrete building block is with cement, Calx, sand, flyash, slag, foaming agent, bubble stabilizer and regulator etc. for primary raw material, through levigate, batching, stirring, pour into a mould, expansion of getting angry, quiet stop, cut, the operation such as the processing of steam press maintenance, finished product and packaging and make, (bulk density is 300 ~ 800kg/m to its light weight3), insulation (thermal conductivity is 0.10 ~ 0.21W/ (m K)), be widely used in the exterior wall filling of xoncrete structure building, interior wall partition, the field such as thermal insulation composite wall body at present.
Waste marble powder is the garbage produced in Marble processing process, and current recycling approach is less, and major part waste marble pruinescence fills up on the spot, and this processing mode had both wasted arable land, again contaminated environment.Waste marble powder be mainly composed of calcium carbonate, and substantial amounts of unsaturated polyester resin can be filled in marmorean polishing operation, the main component of the waste marble powder so produced is just for having filled the calcium carbonate of unsaturated polyester resin, there is good application prospect, it is applied in insulating wall material, New Type Aerated Concrete materials for wall energy-conservation, green can be manufactured.
Summary of the invention
It is an object of the invention to provide a kind of waste marble powder autoclave aerated concrete building block, the waste marble powder containing unsaturated polyester resin that this air-entrained concrete building block produces in the stone of marble surface finish course of processing is for primary raw material, there is the feature of light weight, high-strength, good heat insulating, be a kind of energy saving building material.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of waste marble powder autoclave aerated concrete building block, it is characterized in that, described air-entrained concrete building block be mainly composed of in the stone of marble surface finish course of processing to produce containing the waste marble powder of unsaturated polyester resin, described air entrained concrete includes as follows according to mass percent each component:
Waste marble powder 55～68%,
Cement 6～8%,
Desulfurated plaster 2～5%,
Calx 25～32%,
Aluminium powder 0.08%.
Preferably, in described waste marble powder, the content of unsaturated polyester resin is 1～2%.
Beneficial effects of the present invention has:
The waste recovery recycling problem produced in Marble processing process is more and more urgent, waste stone dust and barren rock material that one medium-scale stone industries garden produces every year just reach more than 1,000 ten thousand tons, a large amount of waste from stackings such as mountain, when wind rises, airborne dust is disorderly, and during rainy season, stone slurry overflows, and surrounding causes serious pollution, existing reutilization technology approach is less, and utilization is little, it is impossible to consume waste stone dust in time, high value added utilization more can not be reached.Waste marble powder is applied in air-entrained concrete building block manufacture by the present invention, this waste marble powder is the waste marble powder containing unsaturated polyester resin produced in the stone of marble surface finish course of processing, unsaturated polyester resin is a kind of thermosetting resin, at a certain temperature can crosslinking curing, join in the raw material such as cement, Calx, the effect of adhesive can be played, improve the overall mechanical property of air entrained concrete, the air entrained concrete light weight made, high-strength, good heat insulating.The present invention has widened the application of waste marble powder, improves its added value, and the recycling for waste stone dust provides a new way.
