Abstract
The invention discloses an aluminum-free autoclaved fly aerated concrete block which comprises the following raw materials, by weight, 100 parts of water, 50-55 parts of fly ash, 20-30 parts of cement, 21-25 parts of glazed hollow bead, 12-17 parts of micro-porous calcium silicate, 10-15 parts of polyester fiber, 12-20 parts of corn stalk, 10-14 parts of a water reducer, 5-7 parts of hydroxyl epoxy resin and 1-4 parts of ethyl cellulose ether. According to the aluminum-free autoclaved fly aerated concrete block, its unit weight is 400-800 kilogram/cubic meter, and its heat conductivity coefficient is usually between 0.04-0.07 kilocalorie/meter*hour*degree and is only 1/4-1/5 of that of clay brick and only 1/5-1/10 of that of common cement concrete. In the North, an aerated concrete block wall of 24 centimetres thick is adopted. Meanwhile, the condition that aluminium powder is used as an air entraining agent in the prior art is avoided; costs are minimized greatly; and low-cost and high-efficiency environmental protection requirements are achieved.
Description
Technical field
The present invention relates to a kind of insulation blocks, belong to building material field.
Background technology
Building block is the artificial bulk of building by laying bricks or stones, and be a kind of novel wall material, profile mostly is right angle hexahedron, also has various shaped body building block.In building block series major dimension length, width or highly have more than one or one respectively more than 365mm, 240mm or 115mm, but segment heights is generally not more than 6 times of length or width, and length is no more than 3 times of height.At present, the insulation blocks on market is rich and varied, but grammar is all in building block, inject lagging material, as thermal insulation mortar etc.Along with people are to the raising of the consciousness of environment protection, energy-saving and emission-reduction have become the important factor in producing.Current insulation blocks, raw materials cost is high, is unfavorable for energy-saving and emission-reduction.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, provides a kind of without aluminium steam pressure powder aerated-block.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of without aluminium steam pressure powder aerated-block, its feed components by weight: 100 parts, water, flyash 50-55 part, cement 20-30 part, glass bead 21-25 part, microporous calcium silicate 12-17 part, trevira 10-15 part, maize straw 12-20 part, water reducer 10-14 part, hydroxyl epoxy resin 5-7 part, cellulose ether 1-4 part.
Preferably; above-mentioned without aluminium steam pressure powder aerated-block, its feed components by weight: 100 parts, water, 52 parts, flyash, cement 27 parts, glass bead 23 parts, microporous calcium silicate 15.5 parts, 15 parts, trevira, maize straw 15 parts, water reducer 11.5 parts, hydroxyl epoxy resin 6 parts, cellulose ether 3 parts.
Beneficial effect of the present invention:
Provided by the invention without aluminium steam pressure powder aerated-block, unit weight is 400-800 kilogram/cubic metre, its thermal conductivity is usually when 0.04-0.07 kilocalorie/rice * between * degree, be only the 1/4-1/5 for clay brick thermal conductivity, for the 1/5-1/10 of portland cement concrete, adopt the wall of aerated concrete block of 24 cm thicks in the north.Meanwhile, avoid in prior art and adopt aluminium powder as air entraining agent, greatly reduce cost, realize with low cost, dynamical environmental requirement.
