Abstract
A concrete is made up of waste foam plastics blocks, fine expanded pearlite, cement, tackifier and water through cutting the waste foam plastics, coating the blocks for flame retardation and mixing it with the others, and features light weight, low cost and high strength. It is suitable for high buildings.
Description
The invention belongs to and use macromolecular material to do the concrete technology field of aggregate.
In Highrise buildings, in order to alleviate load capacity, need to use light weight concrete, some combined wall boards and building block also need use light weight concrete as filler.In the prior art, many light weight concretes are arranged, yet composition has nothing in common with each other.For example, announced in Chinese patent 85100115 patent documentations a kind of " light weight concrete ", for a kind of be the concrete of coarse aggregate with the zeolite, its composition is different with the composition of the present patent application.
The object of the present invention is to provide a kind of is the prescription and the preparation method of the light weight concrete of coarse aggregate with the used foam plastics.
The object of the present invention is achieved like this, a kind of light concrete formulation using waste foam plastics as coarse aggregate and preparation method, and its composition comprises used foam plastics piece coarse aggregate 1, pearlstone fines 2, cement 3, water 4, tackifier 5.
Its prescription (every cubic meter of concrete content) is as follows:
Used foam plastics piece coarse aggregate contains the mm sized blocks 30-50% of 20mm * (25-30), (5-10) the mm sized blocks 70-50% 1-1.1 cubic meter of mm * (10-20).
Pearlstone fines 0.4-0.5 cubic meter
Cement (425-525) 210-250 kilogram
Water 160-185 kilogram
Tackifier 42-50 kilogram
Its preparation technology is as follows:
A, system used foam plastics piece: will through clean, the used foam plastics of sterilising treatment be cut into the piece of following size, wherein, the mm size of 20mm * (25-30) account for 30-50%, (5-10) the mm size of mm * (10-20) accounts for 70-50%.
The shell of making of b, used foam plastics piece is handled: spray organic solvent on the light face of foam-plastic blocks, available tetracol phenixin, benzene and other solvents, the foam-plastic blocks surface corrosion is gone out some apertures, foam-plastic blocks is dropped in the cement stock tank then, the weight ratio of cement and water is 100 in the pond: (25-35), and add 1 kilogram of tackifier (epoxy resin latex), no more than 10 minutes of dip-coating at normal temperatures, make the foam-plastic blocks surface form cement thin shell, but have adhesive capacity and fire retardancy.
C, mix to stir: each composition press the formula rate mixing, stir and block and vibrate 2-3 minute, it is mixed, directly water, also can pour into and make the sheet material building block in the mould.
D, maintenance: by carrying out maintenance with the same method of normal concrete.
Advantage of the present invention is, the intensity height, and ultimate compression strength is greater than 5MPa, and is in light weight, for about the 3KN/ cubic meter, can reduce structural load in a large number, saves main material.Sound-insulating and heat-insulating, waterproof and dampproof, antivibration cracking resistance and fire resistance are good.Can use used foamed plastics in a large number, solve a great problem of administering waste plastic foam goods contaminate environment.Cost is low.Both can directly water, can be used for making wallboard and building block again.Be applicable to Highrise buildings.
