Abstract
Compound haydite building block as wall material, it relates to materials for wall or decorative cover.On the big face (decorative cover) of this figuline building blocks, be covered with a layer thickness and be 5～6 millimeters the synthetic resins slurry of forming by modified acrylate resin emulsion, cement, fine sand, water, blockhouse is with above-mentioned slurry jointing, effectively stopped up capillary channel, so barrier properties is good, avoid the intrusion of water or corrosives, prevented the durable syndrome and the AAR disease of cement effectively, prolonged the buildings life-span.This mortar also is applicable to decorative coat.
Description
The present invention relates to material of construction, relate in particular to materials for wall or decorative cover.
As everyone knows, along with the development of economy and technology, urban architecture is progressively to high stratification development, in order to alleviate basic load, to alleviate the building materials transport pressure, improve the shock resistance of building work efficiency and raising buildings, the development light-weight walling material has become one of major subjects of building materials industry.Come at recent two decades; brick making from fly-ash, small-sized hollow building block; gas concrete; plastering and figuline building blocks etc. are gone into operation in succession and are gone on the market; the hollowization lightweight and the thin-walled property of materials for wall goods greatly reduce the proportion (ratio) of clay-ware, have not only improved construction quality; and saved the energy greatly, and be beneficial to and protect farmland.
Figuline building blocks, to have proportion little, and higher, the ornamental advantage such as strong of intensity is one of the fastest materials for wall of development in recent years.But should see: figuline building blocks made from haydite and sand-cement slurry and the concrete made from rubble and few slurry, not only Chemical Composition is quite similar, and all there is a large amount of capillary porosity ducts on the structure, so in physical environment, factor affecting such as Yi Yin drenches with rain, dewfall, illumination, make body of wall sweat, swollen drum, aging and peel off, come off; Especially when being subjected to corrosive medium (acid, alkali, salt) and invading, can quicken to cause that surface cracking or big area are peeled off etc. " durable syndrome " because of chemical reaction from big G﹠W.In addition, under the condition that water exists, alkalimetal oxide in the cement and sandstone or haydite can produce chemical reaction slowly, and causing crack on concrete or inner structure to be destroyed, this hidden alkali (AAR disease) also is to cause body of wall destructive major reason.The existence of above-mentioned " durable syndrome " and " AAR disease ", to work-ing life of Highrise buildings body of wall or decorative cover be major hidden danger in fact.
The present invention's purpose is: the haydite building block as wall material that a kind of novelty is provided, to improve the quality of figuline building blocks and wall body decoration face, eradicate or alleviate the body of wall or the metope that cause because of " durable syndrome " and " AAR disease " and destroy, prolong the work-ing life of buildings.
The present invention realizes purpose like this.
At haydite commercially available, that make with haydite and sand-cement slurry, on the big face (decorative cover) of building block (specification is not limit), the synthetic resins sand-cement slurry that compound last layer is made up of macromolecule resin emulsion, cement, sand, water, wait do after, the composite haydite building block.Resin emulsion in the described synthetic resins sand-cement slurry is advisable with ACRYLIC EMULSION or acrylic ester emulsion or modified acrylic resin emulsion; Be the best to use poly-ethanol acetal thing with " modified acrylate resin emulsion " (being high-efficiency binder) of acrylate resin emulsion modification gained especially wherein.Take all factors into consideration from cost and effect, adopt preferably that to mix total solid amount that (modification) contain 17～19% acrylate resins and 6～7% polyvinyl formals by acrylate resin emulsion and polyvinyl formal be 23 ± 1% modified acrylate resin emulsion.The optimum formula of resin-bonded mortar is:
Modified acrylate resin emulsion (solid content 23 ± 1%) 1.2～1.4%
Cement (5252#) 22～24%
Sand (fine sand) 61～64%
Frostproofer 0～1%
All the other are water
Described synthetic resins sand-cement slurry, it has the multiple layer thickness on the figuline building blocks to be advisable with 5～6 millimeters; Coating process is best to spray, and is both firm, ornamental, so also should show up as body of wall.
Embodiment and effect:
Example 1: will mix with haydite with the resin cement slurry that above-mentioned prescription is made, through going into the figuline building blocks of making after contour forming, the drying, its intensity is far above the ordinary ceramsite building block, and water-intake rate reduces more than 90%; Because of its cost improves 20%, should not widely adopt.
Example 2: be coated in respectively with above-mentioned prescription slurry on 6 faces of 2 figuline building blockses (thickness 10mm, 6mm), through water immersion test (two days), the water-intake rate of the two is 6～8% of ordinary ceramsite building block, rupture test proof composite bed and building block are very firm, there is not splitting, about 2～3 millimeters of the depth of penetration of water.
Example 3: on the basis of above-mentioned test, determined that the building block coat-thickness is that 5～6mm considers that again figuline building blocks is laid on the reinforced concrete frame more in practicality, so only need there be a big face (decorative cover) coating to get final product, so made the building block of having only the multiple layer of one side, and built test wall, interblock resin-bonded mortar jointing, and do not sprayed resin-bonded mortar at the item face and the end face of multiple layer, make water pouring test after doing, the observation of demolishing walls in seven days, the seepage control of wall effect is identical with example 2.
Adopt modified acrylate resin emulsion to make body of wall coverlay slurry, have advantages such as nontoxic, that valency is low, performance is good.Realize proof: this resin can stop up capillary porosity duct effectively.So can prevent the infiltration of sealing and the intrusion of corrosive medium, fundamentally eliminate the generation condition of " durable syndrome " and " AAR disease ", and can improve the decorative cover quality.
