Description
Technical field
The present invention relates to building material field, particularly belong to a kind of high-strength natural volcanic ash air-entrained concrete building block and
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.

(4) aluminium powder, sugar calcium, polyoxyethylene aliphatic alcohol ether, triterpenoid saponin, zinc stearate, BTA are added appropriate
Water stir, obtain pulpous state and be combined foaming agent, standby；
(5) mixed material that step (2) obtains is joined in blender, under stirring, add additional while add waterside
Agent, after being then sufficiently stirred for 1-2 minute, adds the pulp material that step (3) obtains, and after being sufficiently stirred for 2-5 minute, adds step
(4) the compound foaming agent prepared is sufficiently stirred for, and obtains slurry；
(6) whipping process arranges Insulation, it is ensured that molding temperature during slip casting is at 41-45 DEG C；Slurry is watered
Note to aero-concrete mould, be warming up to 55-70 DEG C and get angry 25-40 minute, pre-at a temperature of 50～70 DEG C after having got angry
Supporting 2～4 hours, after blank strength reaches 0.8～1.1MPa, specification as required is cut；
(7) carrying out steam-cured in the complete base substrate of cutting being delivered to still kettle, the method for maintenance is: heat up 2～3 hours to greatly
Air pressure reaches 0.9～1.2MPa, constant temperature and pressure 6-8 hour, then decrease temperature and pressure 2～3 hours are to room temperature, get product.
The present invention has the following advantages and beneficial effect:
1, the present invention uses utilization industry and agricultural residue as raw material, decreases the waste material pollution to surrounding enviroment, real
Now turn waste into wealth so that resource is maximally utilized.In adjuvant, add homemade compound additive to improve concrete and stir
Water-resistance, frost resistance and durability after mobility when mixing, hardening, with the addition of the pulpous state base material of additive adds again compound
After foaming agent is sufficiently stirred for, it is poured in mould and gets angry, the aluminium powder in compound foaming agent and the acidic activator vinegar in additive
Under the exciting of slag and alkali-activator Borax, gas forming amount increases reaction fully, sodium lignin sulfonate, polyoxyethylene aliphatic alcohol ether,
Under the mutually coordinated effect of triterpenoid saponin, the regular shape of the pore of finished product building block, size uniformly and are evenly distributed.Finished product porosity
Reaching 65%-75%, the pulp material added in formula not only plays potentiation but also play water suction water resistant effect, prepared aerating coagulation
Earth building blocks drying shrinkage value is little, and cracking resistance is good, and water-resistance is good, and particularly intensity is high, and properties all meets Standard.
2, the building block unit weight that prepared by the present invention is at about 600kg/m3, and intensity is high, and drying shrinkage is little, and technique is simple.
3, the air-entrained concrete building block thermal and insulating performance that prepared by the present invention is good, and energy-saving effect is obvious.
