Abstract
The invention relates to a high-strength self-insulation foamed concrete masonry block. The foamed concrete masonry block is characterized by comprising the following raw materials in parts by mass: 20-100 parts of cement, 10-30 parts of mineral powder, 15-50 parts of fly ash, 5-30 parts of micro silica fume, 1-5 parts of polyacrylamide, 1-5 parts of polyvinyl alcohol, 0.5-5 parts of cellulose, 0.5-3 parts of PP fiber, 1-5 parts of water reducer, 1-4 parts of water supplementing agent, 0.5-5 parts of foamed liquid, 0.1-8 parts of accelerator, 0.1-4 parts of triethanolamine, 0.1-7 parts of sodium sulfate and 15-50 parts of mill-tailings.
Description
Technical field
The invention belongs to building materials technology field, be specifically related to a kind of high-strength self thermal insulation foam concrete block.
Background technology
At present, existing foam concrete block all adopts and in concrete haunching, fills the stripping and slicing of benzene plate, when production, there is secondary processing, cause artificial, the waste of the energy and material, extend the duration, and concrete haunching needs artificial maintenance, add and be subject to weather effect man-hour, itself quality is heavier, benzene plate is filled the space of stripping and slicing, between stripping and slicing and stripping and slicing easily there is cold bridge in bonded part, cause indoor calorific loss, there is water of condensation and mouldy Moisture Regain, and with buildings cannot the same life-span, benzene plate is easily to environment in addition, eco-friendly power source, resource is suffered damage and pollution, and fire resistance is lower.
Summary of the invention
The present invention, in order to make up the defect of prior art, provides a kind of indoor industrially to produce, the drum of can avoiding having ftractureed, and reach and the high-strength self thermal insulation foam concrete block of buildings with the life-span.
The present invention is achieved through the following technical solutions:
A kind of high-strength self thermal insulation foam concrete block, its raw material composition by quality proportioning is: cement 20-100 part, breeze 10-30 part, flyash 15-50 part, micro-silicon ash 5-30 part, polyacrylamide 1-5 part, polyvinyl alcohol 1-5 part, Mierocrystalline cellulose 0.5-5 part, PP fiber 0.5-3 part, water reducer 1-5 part, water-repellent agent 1-4 part, bubble liquid 0.5-5 part, accelerating chemicals 0.1-8 part, trolamine 0.1-4 part, sodium sulfate 0.1-7 part, tailings 15-50 part.
Figure of description:
Accompanying drawing 1 is process flow sheet of the present invention.
The invention has the beneficial effects as follows: a kind of high-strength self thermal insulation foam concrete block of the present invention can be realized indoor industrially and produce, adopt pure inorganic materials, consistent with the material property of other buildings, Young's modulus is close, can avoid having ftractureed and rouse, can reach and the same life-span of buildings, and the industrial residue that uses in a large number national policy to allow, as flyash, tailings and breeze, realize energy-conserving and environment-protective and resource recirculation, high with existing foam concrete block phase specific tenacity, hardness is large, thermal conductivity is good, and water-intake rate is low.
