Foamed plastic particles and a water reducer are added into the concrete mix material composed of cement, water, sand and stone chips, and the materials are mixed. The present invention comprises the components (by weight): 1 portion of cement, 0.16 to 0.55 portion of water, 0 to 1.5 portions of sand, 1.5 to 6 portions of stone chip, 0.002 to 0.06 portion of foamed plastic particle and 0 to 0.03 portion of water reducer. The present invention also discloses a manufacturing method of the brick, the water is proportionally added into the cement, the sand, the stone chips, the foamed plastic particles with the particle diameter of 0.5 to 8mm, the water reducer, etc., the materials are mixed into the mix material, the mix material is processed and shaped by brick equipment, the shaped bricks are demolded and are piled for curing, and the bricks can be used after the intensity is reached. The product of the present invention additionally has heat insulation and energy saving effect on the basis of maintaining the original masonry action; as the present invention uses the foamed plastic, the present invention is favorable for environmental protection; the present invention has the advantages of low manufacture cost, high efficiency and simple manufacturing process and considerably saves the engineering cost for reaching the energy saving effect.
Description
Technical field
The present invention relates to a kind of masonry brick that has both load-bearing (separation is gone along with sb. to guard him) and insulation effect, is a kind of insulating brick that a certain amount of foam grain is made that added in concrete mixed material specifically.
Background technology
Existing insulation masonry product mostly is aerating concrete bulk, product is a raw material with levigate quartz sand, lime, cement and gypsum mainly, with the aluminium powder is foaming agent, through batching, stirring, precuring, cutting, maintenance 10～14 hours under High Temperature High Pressure and the fine and closely woven vesicular lightweight aerated concrete goods made.This complex manufacturing, the bubble that produced of getting angry is very unstable, and need carry out steam-cured, relative cost is higher, owing to must be mixed with the lime of more amount in the batching, be used for getting angry with the effect of aluminium powder, determined the ultimate compression strength of the resistance to compression of this product well below concrete; And whitewashing on this masonry surface and often to cause hollowing, is the big common fault of one in the present building operation.In order to reach energy-conservation purpose, there is employing to paste the way that cystose whitewashes again now at wall face, the way that adopts thermal insulation mortar when exterior plaster is also arranged, the former obviously will improve more cost, and the construction technology complexity, and very easily causes to whitewash and flake; Whether correct the latter exist volume problem, and effect is not too obvious.
Summary of the invention
The invention provides a kind of insulating brick that a certain amount of foam grain is made that added in concrete mixed material, this insulating brick has good ultimate compression strength, and has better heat preservation and energy conservation effects.
A kind of concrete bearing insulating brick is characterized in that the concrete mixed material of mainly being made up of cement, sand and aggregate chips, water adds foam grain and water reducer is formed, and its weight proportion is as follows:
Cement 1 weight part, water 0.16-0.55 weight part, sand 0-1.5 weight part, aggregate chips 1.5-6 weight part, foam grain 0.002-0.06 weight part.
Also can add in the above-mentioned composition: flyash 0-0.25 weight part, hardening accelerator 0-0.02 weight part water reducer 0-0.03 weight part.
Described foam grain is that particle diameter is the foam grain of the foam grain of 0.5-8mm or the 0.5-8mm that is processed into by used foam plastics.
The step of the brick producing process of above-mentioned concrete load-bearing insulation is as follows:
A, choose the foam grain of 0.5-8mm or by the used foam plastics piece is made the foam grain that particle diameter is 0.5-8mm with pulverizer;
B, get cement, water, sand, aggregate chips, foam grain, flyash, water reducer and hardening accelerator by the proportioning weighing balance, the error in dipping of each prong material is no more than 2.5%;
Pour aggregate chips, sand, foam grain, flyash, cement after wetting into the stirrer hopper successively after c, the batching, add water and stir into uniform compound, foam grain can drop into after concrete stirs again and be stirred to evenly;
D, compound are delivered to brick equipment with dolly or e Foerderanlage, go into to pave behind the mould demoulding after the moulding of vibrating, and are transported to stacking place, pile piled bricks, also can make of punching block on placenta;
The concrete brick can carry out natural curing or stacking carries out natural curing or steam-cured after e, the moulding, reach intensity product.
The present invention is same to adopt traditional masonry decoration construction technology, but compares with existing concrete aerating bulk, and the present invention has that complete processing is simple, steady quality, have both advantages such as load-bearing (separation is gone along with sb. to guard him) and insulation, cost be relatively low; Solved the recycling problem of porous plastics, turned waste into wealth, can prevent the pollution of the environment effectively, simplified to reaching the related technical measures that building energy conservation is taked; Thermal conductivity hangs down λ=0.26-0.43 (W/ (m.K)), is about ordinary concrete brick 1/4-1/2, meets national present policies and environmental requirement; And be difficult for causing hollowing when whitewashing, saved greatly to reaching the engineering cost of energy-saving effect.The scope of application of the present invention is extensive.
