Description
Technical field
The present invention relates to building material field, particularly belong to a kind of high strenght flyash give up brick and tile air-entrained concrete building block and
Its processing method.
Background technology
Air-entrained concrete building block is that one is light porous, insulation, fire protecting performance good, can follow closely, can saw, can dig and have
There are the New Building Materials of certain shock resistance.The production principle of air-entrained concrete building block is to utilize siliceous material, calcareous material,
Be additionally incorporated appropriate regulation material and a small amount of material admixture foaming agent (aluminium powder) of getting angry, by dispensing, stir, pour into a mould, precuring,
The light porous silicate product that the technical processs such as cutting, steam pressure, maintenance are made.Because it contains the most uniform and thin after getting angry
Little pore, therefore named air entrained concrete.Pore in air-entrained concrete building block accounts for the 60%-75% of its volume.Therefore, pore
Shape, size, quantity and distribution almost affect all properties of air-entrained concrete building block, such as intensity, unit weight, absorb water, protect
Warm, heat insulation and sound insulation etc..
At present, air-entrained concrete building block has an insoluble technical problem in producing, and aerated blocks mould rate of collapsing is higher, leads
Causing aerated blocks qualification rate about 80%, the insufficient strength of the finished product processed, cause collapsing mould and inadequate main of product intensity
Reason be exactly existing foaming agent get angry weak effect, get angry uneven, pore in irregular shape, size is uneven, distribution not
Uniformly.Therefore studying how by scientific matching and the adjustment of technique of adjuvant of getting angry, final production goes out to get angry uniformly, aperture shape
The air-entrained concrete building block that shape, size, quantity and distribution are the most more satisfactory, is that current air entrained concrete researchers are anxious to be studied
Problem.
