Abstract
The invention provides a low-cost aerated concrete block, and belongs to the technical field of production and preparation of building materials. The low-cost aerated concrete block is prepared through the following raw materials in parts by weight: 5 to 10 parts of portland cement, 3 to 5 parts of sulphoaluminate cement, 45 to 50 parts of fly ash, 50 to 70 parts of fine sand, 0.05 to 1 part of sodium sulfate, 10 to 50 parts of inorganic light porous material, 5 to 10 parts of anti-crack fiber, 10 to 25 parts of ash calcium, 1 to 3 parts of early strength polycarboxylate superplasticizer, 1 to 3 parts of gypsum, 1 to 10 parts of foaming agent, and a proper amount of water. According to the low-cost aerated concrete block, sodium sulfate is adopted in the formula, so that the early strength effect of the low-cost aerated concrete block is great, the strength can be improved by 28d, and the activity of the fly ash also can be excited; the inorganic light porous material is added, so that the reduction of volume weight can be reduced, and thermal conductivity of the low-cost aerated concrete block is lowered; the anti-crack fiber is added so as to reduce the fracture and damage rate of the material and improve the strength; the early strength polycarboxylate superplasticizer is added so as to reduce the dose of water used for agitating the material and enables the material strength to be reached in advance; stearic acid has the effects of strengthening and proofing water. The low-cost aerated concrete block is rational in material ratio and low in cost and has a good effect.
Description
Technical field
The present invention relates to a kind of building field air-entrained concrete building block.
Background technology
In current air-entrained concrete building block production formula technology, mainly contain sand, cement, gypsum, flyash, calcium oxide, alkali and whipping agent, the post-foaming production technique that the aluminium powder of take is representative.
The temperature of goods that this production formula determines, the denseness of slurry affect foamed time and gas release, and the relation because of setting time produces deaeration and the inconsistent phenomenon of proportion again.
Often cause because of quality influence such as air-entrained concrete building block and goods water-intake rate thereof are relatively large, the high qualification rate of finished product breakage rate is low.
Because production unit drops into hugely, and production cycle length, energy consumption very high (cost is large), floor space are large again.And production technology is backward,
Very strict with the specification of quality of masonry mortar and plastering mortar when air-entrained concrete building block is constructed, each side unfavorable factor hinders the development that this (air-entrained concrete building block and goods thereof) technology is produced and applied simultaneously.
Summary of the invention
In order to solve the technical problem of above-mentioned existence, the invention provides the low-cost air-entrained concrete building block technology of a kind of pre-frothing production technique.
The object of the invention is to be achieved through the following technical solutions: a kind of low-cost air-entrained concrete building block, by following raw material, made by weight:

Also comprise 1～3 part of stearic acid.
Also comprise sodium carbonate 1-3 part.
One or more in the described optional expanded and vitrified small ball of light inorganic porous body material, pearlstone, Calucium Silicate powder and diatomite.
Beneficial effect of the present invention: in the present invention's formula, adopt sodium sulfate not only to make product early effective by force, and the raising of 28d intensity, can excite flyash activity simultaneously; After adding light inorganic porous body material, can, by low production unit weight, reduce product thermal conductivity; Add anti-crack fiber can reduce Materials Fracture breakage rate, increase anti-intensity; Add poly carboxylic acid early strength water-reducing agent can reduce the water consumption of mixing honest material, can reach in advance the strength of materials simultaneously; Stearic acid has enhancing, waterproof effect; Hypochlorite (being specially Losantin or clorox, potassium hypochlorite) can decompose the effect of promotion hydrogen peroxide, can alonely be whipping agent again; Sodium carbonate promotes aluminium powder foamable reaction; Gypsum is as flyash alkalescence exciting agent.
Technical solution of the present invention and current existing production have advantages of:
(1) compare with current production technology, simplify processing step, save a large amount of expensive device investments, then save a large amount of power consumptions and floor space, material cost reduces relatively;
(2) adopt storeroom chemical principle, complex cement and grey calcium, utilize and mix compounding technology more, make product strength and setting time complementary;
(3) flyash improves material fluidity, replaces cement consumption.Add after flyash excitant, can excite flyash activity;
(3) material is widely applicable, selects conveniently, reduces transportation cost;
(4) cut block materials fragmentation, ball milling operation, directly utilize powder to use, reduce the environmental pollution that manufactures a finished product;
(5) it is basic identical that products production of the present invention and currently available products are produced general-purpose equipment, but adopt powder to produce, and cuts block of material disintegrating apparatus; Again because of formed at normal temp maintenance, cut autoclave, Boiler Steam is heated and steamed oxygen processing step, improves production safety coefficient; Not only save equipment investment, and save energy consumption;
(6) in production, add fiber and light inorganic porous body material, when reducing finished product breakage rate, by adding in product, there is porous light material, reduce material thermal conductivity, improve heat insulation effect;
(7) in raw material, can add one or more light inorganic porous body materials.Light inorganic porous body material is outside unicellular structure, and other non-light inorganic porous body material component also becomes microporous foam and parcel light inorganic porous body material aborning, makes finished product have hydrophobic function simultaneously, has multilayer flashing function, reduces thermal conductivity;
(8) finished product is inorganic system, and fire-protection rating is A level (not firing), widely applicable; Construction can be used universal polymkeric substance plastering mortar and masonry mortar.
