Abstract
The invention discloses an aluminum-free autoclaved aerated building block. The aluminum-free autoclaved aerated building block is prepared from the following raw materials in parts by weight: 100 parts of water, 40-45 parts of cement, 35-45 parts of gypsum, 21-27 parts of silica sand, 10-15 parts of saw dust, 10-15 parts of corn straws, 8-15 parts of a water reducing agent, 6-10 parts of micro-porous calcium carbonate, 2-7 parts of hydroxyethyl cellulose, 3-5 parts of sodium polyacrylate and 0.5-2 parts of polyester fibers. According to the aluminum-free autoclaved aerated building block disclosed by the invention, volume-weight is 400kg/cm<3> to 800kg/cm<3> and the heat conductivity coefficient is generally between 0.04 kcal/m*h*DEG to 0.07 kcal/m*h*DEG which is 1/4 to 1/5 of that of clay and 1/5 to 1/10 of that of common cement concrete. In the north, an aerated concrete block wall body which is 24cm thick is adopted. Meanwhile, the use of aluminum powder as an aerating agent is avoided, so that the cost is greatly lowered, and environmental protection requirements on low cost and high performance are realized.
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 sand aerated-block.
Object of the present invention carrys out specific implementation by the following technical programs:
A kind of without aluminium steam pressure sand aerated-block, its feed components by weight: 100 parts, water, cement 40-45 part, gypsum 35-45 part, silica sand 21-27 part, wood chip 10-15 part, maize straw 10-15 part, water reducer 8-15 part, microporous calcium silicate 6-10 part, hydroxyethyl ether cellulose 2-7 part, sodium polyacrylate 3-5 part, trevira 0.5-2 part.
Preferably, above-mentioned without aluminium steam pressure sand aerated-block, its feed components by weight: 100 parts, water, cement 40 parts, 40 parts, gypsum, silica sand 25 parts, wood chip 12.5 parts, maize straw 11 parts, water reducer 10.5 parts, microporous calcium silicate 7 parts, hydroxyethyl ether cellulose 5 parts, sodium polyacrylate 3.5 parts, 1 part, trevira.
Beneficial effect of the present invention:
Provided by the invention without aluminium steam pressure sand 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.
