Abstract
The invention relates to a paving material, in particular to a paving material produced by utilizing building garbage. The paving material consists of the following components in parts by weight: 65-80 parts of regenerative aggregate, 10-30 parts of auxiliary material, 1.0-5.0 parts of additive and 200-400 parts of water. The paving material has the beneficial effects that: by using the paving material produced by using the building garbage, which is provided by the invention, the standards of plant use are all met on aspects such as compressive strength, rupture strength, softening degree, carbonization coefficient and the like; moreover, sodium carbonate or calcium carbonate is added; the compressive strength and the rupture strength of the paving material are improved; according to the paving material, the building garbage is utilized; the cost for constructing a road is greatly decreased; meanwhile, the building garbage can be also recycled; a low-carbon environment-friendly role is played; and the paving material has a favorable economic effect and a favorable social effect, and is suitable to popularize.
Description
Technical field:
The present invention relates to a kind of pavior, more specifically a kind of pavior that utilizes building waste to produce.
Background technology:
The various resources that comprise that cause for a large amount of building wastes, environment and society are in interior problem, a large amount of scholars have clearly recognized, at present domestic for the most of processing mode that adopts landfill of building waste, take Hong Kong Building rubbish filler storehouse as example, Tseung Kwan O's filler storehouse design capacity in Hong Kong is 1,080 ten thousand tons, storage is above 7,500,000 tons now, filler storehouse, Tunmen design capacity is 6,500,000 tons, storage is own above 4,500,000 tons now, the Hongkong government has been that building waste filler Kuku is completely for suffering from worry, so adopt the landfill building waste not only to take a large amount of arable lands, and resource produced great waste, therefore need to strengthen and return again for building waste
Receive the research that utilizes.Although domestic building waste is recycled started late, in conjunction with some external advanced experiences, develop still very fast.
Just there is successively the researchist to propose the various approach that are recycled about building waste since the initial stage nineties, and applied for Patents.Sum up its approach that is recycled mainly to reclaim and it is broken for the aggregate of certain particle diameter, and carry out corresponding reutilization measure for the aggregate of various differing materials different-grain diameter varying strengths, they are carried out rationally effectively recycling, obtained preferably resource, environment, economic and social benefit.
The bed course that is used for doing the temporary construction road that common building waste has, still to clear up the refuse tip at last, can not reasonably be utilized and the environmental pollution that causes and waste economically the invention provides a kind of building waste that utilizes and carry out the method that pavior is produced in recycling for present building waste.Building waste is used for the cost that pavior can reduce constructing road greatly, also can in addition recycle of building waste, play to a great extent environmental-protection function simultaneously.
Summary of the invention
For above deficiency, the invention provides a kind of pavior that utilizes building waste to produce, the present invention utilizes building waste, greatly reduces the cost of constructing road, also can recycle building waste simultaneously, plays the low-carbon environment-friendly effect.
Owing to use waste construction material as regeneration aggregate, its water-intake rate is than large many of natural aggregate concrete, and mainly to be that sand-cement slurry content is higher in this regeneration aggregate cause for this.Therefore when the actual production regeneration concrete, must note the high water absorbing capacity problem of regeneration aggregate, otherwise can affect production, use and the physico-mechanical properties of regenerated aggregate concrete.The regenerative mixed aggregate has larger water-intake rate, can reduce concrete flowability as aggregate, is compensated so tackle it.The present invention adopts additional water consumption method, namely at first measures aggregate 1h water-intake rate, and add this part water yield in the mixing concrete water yield.
The present invention is achieved by the following technical solutions: a kind of pavior that utilizes building waste to produce is comprised of the following component of counting by weight: regeneration aggregate 65-80 part, subsidiary material 10-30 part, additive 1.0-5.0 part, water 200-400 part.
The particle diameter of above-mentioned regeneration aggregate is the 0.2-20 millimeter.
Above-mentioned subsidiary material are cement.
Above-mentioned additive is calcium carbonate or yellow soda ash.
Above-mentioned a kind of preparation method of the pavior of building waste production that utilizes is: after building waste being removed the impurity such as timber, iron, daily necessities and plastics, obtain regeneration aggregate through pulverizing; Getting particle diameter is regeneration aggregate 65-80 part of 0.2-20 ㎜, adds entry 200-400 part after subsidiary material 10-30 part roasting to 800 ℃, stirs also to add additive 1.0-5.0 part, after fusing is finished and get final product.
Above-mentioned a kind of preparation method of the pavior of building waste production that utilizes is: after building waste being removed the impurity such as timber, iron, daily necessities and plastics, obtain regeneration aggregate through pulverizing; Get particle diameter and be 70 parts of the regeneration aggregates of 0.2-20 ㎜, add 200 parts of entry after 29 parts of roastings to 800 of cement ℃, stir and also add 1.0 parts in yellow soda ash, after fusing is finished and get final product.
The invention has the beneficial effects as follows: the pavior that the present invention uses building waste to produce, all reached the standard of production and application at fermentation such as ultimate compression strength, folding strength, softening degree and carbonation coefficients, and yellow soda ash or calcium carbonate have been added, ultimate compression strength and the folding strength of above-mentioned pavior have been improved, the present invention utilizes building waste, greatly reduce the cost of constructing road, also can recycle building waste simultaneously, play the low-carbon environment-friendly effect, have good economic benefits and social effect, be suitable for promoting.
