Description
Technical field
The present invention relates to building material technical field more particularly to a kind of preparation sides of high-durability air-entrained concrete building block
Method.
Background technique
Air-entrained concrete building block is a kind of new green environment protection energy-saving material, be a kind of achievable resource, environment, performance and
The environment-friendly energy-saving building materials of cost optimal combination, the green building material new varieties that country widelys popularize.
Currently, the generally existing compression strength of air-entrained concrete building block production process is low, lead to problems such as durability poor.
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of systems of high-durability air-entrained concrete building block
Preparation Method, gained air-entrained concrete building block density is low, and compression strength is high, and durability is good.
A kind of preparation method of high-durability air-entrained concrete building block proposed by the present invention, includes the following steps:
S1, flyash, zeolite powder, vermiculite power, hydroxy silicon oil are uniformly mixing to obtain mortar；
S2, into the mortar in stirring, addition lime, gypsum, cement mixing are uniform, add aluminium powder, air entraining agent
Continue to stir to get slurry；
S3, slurry is injected in mold, steam press maintenance obtains high-durability air-entrained concrete building block.
Preferably, in S1, flyash, zeolite powder, vermiculite power, hydroxy silicon oil weight ratio be 100-200:20-35:12-
25:1-2.
Preferably, in S2, whipping temp is 40-50 DEG C.
Preferably, in S2, mortar, lime, gypsum, cement, aluminium powder, air entraining agent weight ratio be 150-230:4-12:4-
12:20-40:1-2:1-4.
Preferably, in S2, the steam press maintenance time is 10-20h, and steam press maintenance temperature is 200-210 DEG C.
Flyash, zeolite powder, vermiculite power are mixed into aggregate first by the present invention, by mashing under the action of hydroxy silicon oil
The mortar formed afterwards, is mutually uniformly dispersed, and cooperation lime, gypsum, cement act on forming close and firm skeleton, improves steaming
The pore structure of standard brick system is pressed, not only brick is impervious strong, but also can effectively improve the compression strength and flexural strength of brick,
Flyash processing problem is also solved, reduces flyash and is polluted to city bring, and aluminium powder is compounded with air entraining agent, is to mention
For enough gas forming amounts, guarantee full mould and yield, reduce product bulk density, and is not in that slurry collapses mould and green body shrinkage phenomenon.
Through detecting, the dry density of present invention gained air-entrained concrete building block is 540-580kg/m3, compression strength 10-
12Mpa, stomata average diameter < 0.2-0.3mm, drying shrinkage value < 0.32-0.38mm/m, compression strength loss rate < after jelly
12%, dry state thermal coefficient < 0.13W/ (mK), qualification rate > 98%, parameters are above the B07 of national standard formulation
The requirement of grade autoclave aerated concrete building block high-class product.
