Abstract
The invention discloses a method for manufacturing regenerative solid bricks with MU7.5 by utilizing construction waste in the field of construction materials. According to the method, the solid bricks comprise the following compositions: waste bricks and waste concrete in the construction waste, Portland cement and water, the regenerative solid bricks with the strength of MU7.5 can be manufactured by the construction waste through five procedures of sorting, crushing and screening into waste brick powder and waste concrete powder, airing, forming, maintaining and the like, wherein the particle sizes of the waste brick powder and waste concrete powder are less than 4.75mm. The method is a green synthesis process, and through tests, the average compressive strength is 8.8Mpa, the rupture strength is 2.2Mpa, the water absorption rate is 22%, the volume density is 1703kg/m<3>, the softening coefficient is 77.7%, and all the coefficients can achieve the national standard requirements.
Description
Technical field
The invention belongs to building material field, be specifically related to a kind of method of utilizing building castoff to prepare MU7.5 regeneration solid brick.
Background technology
Flourish along with China's building industry, urbanization and process of industrialization are constantly pushed ahead, and have caused the generation of a large amount of building castoffs, to national energy, have brought heavy burden, and building energy conservation has become a fundamental state policy of engineering construction.Meanwhile, China also faces again buildings and resources demand rapid growth and the day by day deficient serious problems of material of construction.Therefore, how rationally disposal and utilization building castoff, reduces the waste of land resources, realizes the recycle of resource, is building material field problem demanding prompt solution.Utilizing building castoff preparation regeneration solid brick and apply in construction work, is one of effective way realizing China's buildings and resources recycle.In prior art, as " utilize building castoff prepare the method for MU5 regeneration solid brick (number of patent application: 201310091800.4) " the useless brick of Recycle building prepares body of wall solid brick, solved to a certain extent the problem of the recycle of part building castoff.But the main building castoff of its utilization is useless brick, and building castoff is except useless brick, and most waste is waste concrete, so also could not utilize more fully building castoff.Therefore, be necessary to propose a kind of more can be fully and rationally utilize building castoff to prepare to regenerate the method for solid brick, to reach in resource circulation utilization, reduce production costs more, realize environmental protection and building energy conservation.
Summary of the invention
The technical problem to be solved in the present invention is to provide and a kind ofly can makes full use of the method that building castoff is prepared MU7.5 regeneration solid brick, this regeneration solid brick is more than not only intensity reaches the 7.5Mpa of national regulation, and quality is light, water absorbing properties is good, combat a natural disaster that change ability is strong, environmental protection, production cost are low, has very high economic benefit, social benefit and ecological benefits.
The present invention solves the problems of the technologies described above by following technical solution:
Utilize building castoff to prepare a method for MU7.5 regeneration solid brick, its raw material forms with mass parts and the preparation process of each raw material as follows:
The composition of raw material and the mass parts of each raw material are:
Preparation process is:
(1) sorting: useless fragment of brick and waste concrete block in building waste are picked out;
(2) broken, screening: to (1) useless fragment of brick and waste concrete block broken, the screening respectively of gained of step, obtain useless brick powder and waste concrete powder;
(3) airing: by the (2) useless brick powder of gained and waste concrete powder airing 2-3 days respectively of step, remove the moisture in its hole;
(4) moulding: add in proportion cement and water after (3) the useless brick powder of gained and waste concrete powder are mixed in proportion, stir 30s by step, after stirring again 1min, pack into immediately in die trial, and be placed on shaking table and vibrate, vibrate after 1～2min die trial upper surface slurry is erased, make test specimen upper surface smooth;
(5) maintenance: specimen molding after one day form removal piling carry out maintenance, within first 7 days, carry out artificial water seasoning, within 21 days afterwards, carry out natural curing, altogether maintenance is 28 days.
The particle diameter of described useless brick powder and waste concrete powder is all less than 4.75mm.
Stirring velocity during moulding is 48 revs/min.
The present invention is usingd and is given up brick and waste concrete as main raw, adopts water and cement to prepare MU7.5 regeneration solid brick as gelling material.Regeneration solid brick prepared by the present invention can meet the requirement of strength grade, and because its moiety is only containing fine aggregate, the solid brick list brick weight that makes to regenerate has reduction by a relatively large margin, has advantages of light weight.Have advantages of that production cost is lower simultaneously, economic benefit, social benefit and ecological benefits higher, meet China's strategy of sustainable development and the requirement of green building principles and policies.
Embodiment
The present invention utilizes building castoff to prepare the method for MU7.5 regeneration solid brick, be to using useless brick in building waste and waste concrete to form and gather materials as fine aggregate through broken, screening, in addition a certain amount of cement and appropriate water are prepared the regeneration solid brick that strength grade is 7.5Mpa.The composition of its raw material and the mass parts of each raw material are: 15 parts of useless bricks, 30 parts of waste concretes, 5 parts of silicate cements, 4 parts, water.
The preparation process of MU7.5 regeneration solid brick is:
From building waste, pick out useless fragment of brick, pack fragmentation in crusher into, screen out the fragment of brick that particle diameter is greater than 4.75mm, obtain useless brick powder.
From building waste, pick out waste concrete block, pack fragmentation in crusher into, screen out the concrete blocks that particle diameter is greater than 4.75mm, obtain waste concrete powder.
The recycled fine aggregate that above step is formed is airing 2-3 days respectively, by moisture removal in its hole.
To give up in proportion brick powder and waste concrete powder packs in stirrer, the pre-30s that stirs, then add in proportion cement and water again to stir, after stirring 1min, pack into immediately in die trial, and be placed on shaking table and vibrate, vibrate after 1～2min die trial upper surface slurry is erased, make test specimen upper surface smooth.
