Description
Technical field
The present invention relates to building material manufacture field, and in particular to it is a kind of it is high-strength, block water air entrained concrete building block and
Preparation method.
Background technology
New Building Materials are caused a new generation's upgrading construction material, main bag on the basis of traditional building material
Include novel wall material, heat preserving and insulating material, waterproof and sealing material and decorating and renovating material etc..When the low-carbon epoch arrive,
In the case where country advocates energy-saving, Transformation Development overall background, green low-carbon, energy-conserving and environment-protective, which have become building material, to return
The mission kept away.For this, with it is green, sharp it is useless, heat-insulated, insulation, fire prevention, it is light, high-strength, substitute, cost is cheap, section is native, save
Ground therefrom obtains huge development new opportunities for the building material of target.The industrial output value of building material is more than 600,000,000,000 yuan, year
14% is grown beyond, family more than 5000 of working enterprise.At present, constantly there is building material to be developed, particularly some Composites,
Multifunction, energy-saving, greenization, the building material of high-strength light occupy the proportion of traditional construction material more than 50%.
Air-entrained concrete building block as a kind of novel wall material, due to good thermal and insulating performance, it is in light weight,
The advantages that anti-seismic performance is good, applied in the filling wall and load bearing wall of building, to improving the heat-insulating property of building structure, reducing
Building load has obvious action.Air-entrained concrete building block is mainly with sand, rubble, flyash and containing silicon tailings and calcareous material
The gel of material is primary raw material, fills foaming agent aluminium powder, passes through the works such as dispensing, stirring, cast, precuring, cutting, steam pressure, maintenance
Light porous silicate product made of skill process.
But when specifically used, air-entrained concrete building block is because having more insertion space, therefore it is high to absorb water, it is difficult to hinders
Long-term immersion is kept off, thus it is high to the waterproof requirement of wall.In addition, air-entrained concrete building block surface strength is low, surface holds
Powder is easily played, is not easy to preferably bond with mortar during use, it usually needs special mortar is bonded.Therefore, it is existing to add
Gas concrete segment is high to use and construction technical requirement, is widely applied so as to hinder it.
Chinese invention application number 201510754705.7 discloses a kind of good autoclave aerated concrete building block of mechanical strength
And preparation method thereof, the hydroxyl to dissociate in cellulose is enclosed by carrying out acetylization reaction to cypress fiber, improves material
Hydrophobic performance and heat endurance, then coordinate physical modification method to add other active ingredients, improve fiber steam pressurized
Durability and dispersiveness in concrete so that aerated-block has splendid mechanical strength, excellent heat-resisting quantity and water proofing property
Energy.But the hydrophobic performance of material and heat endurance depend on cypress fiber progress acetylization reaction degree in the program, furthermore
Hardening strength is carried out using string to be limited.
Therefore, the high technological deficiency of hygroscopic, low intensity, construction requirement be present for existing air-entrained concrete building block, open
Send out new preparation method a kind of and can effectively manufacture and produce that high-strength, the air-entrained concrete building block that blocks water is significant.
The content of the invention
The defects of hygroscopic, low intensity, high construction requirement be present for existing air-entrained concrete building block, the present invention proposes one
Kind is high-strength, block water air entrained concrete building block and preparation method, and gypsum, quick lime, cement, flyash are ground into particle diameter 10
Below μm, make its activation, add papermaking wastewater and aluminium powder, got angry by aluminium powder in slurry, it is organic saponified in papermaking wastewater
Foaming, fine active calcium material is promoted to generate spherical afwillite hard wall material with siliceous material hydro-thermal, so that gram
Taken existing air-entrained concrete building block and the high technological deficiency of hygroscopic, low intensity, construction requirement be present, obtain it is high-strength block water plus
Gas concrete building blocks.
To solve the above problems, the present invention uses following technical scheme：
On the one hand offer one kind is high-strength, block water air entrained concrete building block, and the air entrained concrete building block is by including under
