Description

The concrete building material that is used to spray
Technical field
What the present invention relates to is a kind of gunning concrete of building material technical field, and specifically, what relate to is a kind of concrete building material that is used to spray.
Background technology
At present, the construction of concrete material realizes in the mode of cast that usually this makes troubles in some particular surroundingss and occasion construction to it, especially the construction of the body of wall of some facades and Tunnel Engineering.Although for many years, sprayed concrete is in some application of engineerings such as tunnel, and phenomenon is more serious ash to occur falling in course of injection, come off etc., causes the slip loss serious, and environment is made a big impact.And sprayed concrete only is confined to engineerings such as tunnel, seldom sees in engineerings such as residential houses.The material that is used for the body of wall spraying, usually also only be confined to the coating of some decoration functions, as patent publication No.: 02115354.X, patent name: cement-based polymer paint powder, this patent proposes a kind of surface material that is used to spray with polymkeric substance and cementitious composite realization, but only is used for decorating and cement basic layer.
Along with country improves the requirement of building energy conservation, building all need be considered power saving.From in the market, mainly be to adopt some eps foam particle mortars and outsourcing EPS warming plate to realize building energy conservation.And in construction process, the most difficult is EPS material and cement matrix adhesion problem.
Find through literature search prior art, as patent publication No.: 02153346.6, patent name: polyurethane heat insulating wall and construction technology, this patent is difficult to problems such as control at being difficult in the rigid urethane foam external thermal insulation wall body construction with cement matrix bonding and surface layer planeness, the multiple layers of different materials combination construction is proposed, complex process.Patent publication No. and for example: 200810063805.5, patent name: EPS plate cast-in-place concrete system wall thickness lock lever, this patent adopts special-purpose thickness of wall body lock lever that its exterior wall heat-preserving system is reinforced, and constructs loaded down with trivial details and can not constitute an integral body with concrete structure.Therefore, a kind ofly be used to be painted on the EPS warming plate and form the hold concurrently concrete sheath coat of decoration functions of the closely knit protective layer of structure and seem very necessary and valuable, but yet there are no related products and report in the market.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art; a kind of concrete building material that is used to spray is provided; it is solved in the existing vertical plane wall body piercing surface construction lack a difficult problem that exists in direct spray material and the EPS warming plate construction process; can be painted on and form the closely knit protective layer of structure on the EPS warming plate, have excellent waterproof, prevent fires and increase substantially EPS warming plate weight capacity.
The present invention is achieved by the following technical solutions, and each component of the present invention and weight percent thereof are:
Magnesium oxide 7-13%
Potassium primary phosphate 25-35%
Quartz sand 15-45%
Flyash 15-25%
Boric acid or borax or citric acid 1-2%
Wooden calcium sulfonate or the 1-2% of wooden sodium sulfonate
The described magnesium oxide burned magnesium oxide of attaching most importance to, its solubility constant require to be controlled to be 5-25, and grain diameter is controlled in the 8-10 micrometer range.
Described potassium primary phosphate is a technical grade, and purity requirement is more than 98%.
Described flyash is II level flyash.
Described quartz sand adopts to meet the common building sand that JGJ52-92 " regular concrete sand quality standard and test method " requires, the grating by strictness control sand with the sand classification after remix, with the density of raising spray material.Meet particle diameter and grating requirement down:
2.500～5.000mm 0～6% (weight ratio)
1.250～2.500mm 20～35% (weight ratio)
0.315～1.250mm 55～65% (weight ratio)
＜0.315mm 10～15% (weight ratio)
The fineness modulus that is sand is in 2.7～2.9 scopes.
Described boric acid or borax or citric acid are the commercially available prod, and its purity is greater than 90%, and water content is less than 0.5% powder.
Described wooden calcium sulfonate or wooden sodium sulfonate are the commercially available prod, and its purity is greater than 95%, and water content is less than 0.5 powder.
The preparation method of the above-mentioned concrete building material that is used to spray of the present invention is: claim required heavy burned magnesium oxide, potassium primary phosphate, boric acid (or borax, citric acid) and wooden calcium sulfonate (or wooden sodium sulfonate) by formula rate, in stirrer, stir, form product, pack.When use the working-yard, according to base material and performance requriements, can be by 1% admixture fine PP fiber of product weight, the mixing water that adds material weight 15～25% then fully stirred 2-3 minute in stirrer, utilize spraying equipment to carry out spray treatment, spraying process is controlled in 30 minutes and finishes.In case after the spraying, this product thick and very fast generation cohesive force that will become sticky can be owing to deadweight is fallen.The present invention utilizes heavy burned magnesium oxide and potassium primary phosphate that chemical reaction takes place fast to form high cohesive force and high strength structure system, and firm must being bonded in forms integral body on cement concrete metope or the EPS warming plate.Magnesium oxide and potassium primary phosphate are with after water mixes, be swift in response, be easy to occur the rapid coagulation sclerosis, for effectively controlling the setting and harden time, admixture boric acid (or borax, citric acid) is to control heavy burned magnesium oxide dissolution rate in water, simultaneously admixture wooden calcium sulfonate (or wooden sodium sulfonate) is with the potassium primary phosphate dissolution rate in water that slows down, thereby realizes that this system finishes spraying in the specified time.
The invention has the advantages that: the material of rapid construction of a kind of energy and building is provided, compares with traditional cement concrete, it has excellent viscosifying power and good volume stability, waterproof and fire resistance property; Characteristics such as be sprayed on the compound system that forms on the EPS warming plate, the materials for wall that can directly use as partition wall has the heat insulating effect, and construction technology is simple simultaneously, and speed of application is fast.
