Description
Technical field
The present invention relates to the foamed concrete field, relate in particular to a kind of foamed concrete additive and foamed concrete.
Background technology
For construction material, its performance index mainly are weight, intensity, heat insulating, sound insulation etc.For the building energy conservation environmental protection requirement, need that materials for wall is in light weight, intensity is big, heat insulating, sound insulation.And foamed concrete can satisfy above-mentioned condition preferably.Concrete is through after expanded, and heat insulating and sound-proofing properties index improve greatly, and the weight of unit volume also can be reduced to concrete below 1/3rd.
In the foamed concrete of prior art was produced, the additive of interpolation (foaming agent) was divided into two kinds of plant type and animal-types.In the practical application, the plant type additive can make the foamed concrete undercapacity, and the foam effect less stable produces the situation that expansion rate is not enough and foam is uneven sometimes simultaneously, can directly influence the use and the yield rate of product like this.Though animal-type additive foam effect is stable, production cost is higher, has limited the use field.Because above-mentioned deficiency has restricted the application and the development of foamed concrete.
Therefore, need provide a kind of foamed concrete additive and foamed concrete to address the above problem.
Summary of the invention
In order to address this problem, the invention discloses a kind of foamed concrete additive, said components of additives mass ratio is following: sodium lauryl sulphate: 3.5%; Dimethyl dodecyl amine oxide: 0.8%; Thickening material: 5%; Water glass: 5%; Water reducer: 0.3%; Water: 85.4%.
Preferably, said thickening material is a thickening material 638.
Preferably, said thickening material is selected from a kind of in sodium bentonite, organobentonite, zeyssatite, attapulgite soil, molecular sieve, silicon gel, gelatin, tree elastomer, yolk, agar, SEPIGEL 305, Z 150PH, Vinylpyrrolidone polymer, polyoxyethylene, carbomer, ROHM, ZX-I, polyacrylic ester copolymer emulsion, cis-1,4-polybutadiene rubber, styrene-butadiene rubber(SBR), urethane, modification polyureas, the low-molecular polyethylene wax.
Preferably, said water reducer is selected from lignosulfonic acid sodium salt water reducer, naphthalene series high-efficiency water-reducing agent, aliphatic high-efficiency water reducing agent, amino high high efficiency water reducing agent, a kind of in the high-efficiency water-reducing agent of poly-carboxylic acid.
The invention also discloses a kind of foamed concrete, the constituent mass of said foamed concrete is such as following: cement: 15%-17%, and fine sand: 10%, flyash: 50%, water: 20%, through 1: 35 water-reducible additive: 3%-5%.
Foamed concrete additive of the present invention and foamed concrete, strong to the flexibility of cement, the intensity of product is high, and expansion rate is high, and froth stability is strong, has reduced production cost, and nonpoisonous and tasteless difficult decomposition stores convenient transportation.
In the summary of the invention part, introduced the notion of a series of reduced forms, this will further explain in the embodiment part.Content part of the present invention does not also mean that key feature and the essential features that will attempt to limit technical scheme required for protection, does not more mean that the protection domain of attempting to confirm technical scheme required for protection.
Below specify advantage of the present invention and characteristic.
Description of drawings
Do not have.
Embodiment
In the description hereinafter, a large amount of concrete details have been provided so that more thorough understanding of the invention is provided.Yet, it will be apparent to one skilled in the art that the present invention can need not one or more these details and be able to enforcement.In other example,, describe for technical characterictics more well known in the art for fear of obscuring with the present invention.
In order thoroughly to understand the present invention, detailed structure will be proposed in following description.Obviously, execution of the present invention is not limited to the specific details that those skilled in the art has the knack of.Preferred embodiment of the present invention is described in detail as follows, yet except these were described in detail, the present invention can also have other embodiments.
Below embodiments of the invention are done detailed description.
The present invention at first discloses a kind of foamed concrete additive, and this additive is the aqueous solution, and its constituent mass is such as following:
Sodium lauryl sulphate (K12): 3.5%;
Dimethyl dodecyl amine oxide: 0.8%;
Thickening material: 5%; This thickening material can be thickening material 638; The perhaps thickening material of other types, for example sodium bentonite, organobentonite, zeyssatite, attapulgite soil, molecular sieve, silicon gel, gelatin, tree elastomer, yolk, agar, SEPIGEL 305, Z 150PH, Vinylpyrrolidone polymer, polyoxyethylene, carbomer, ROHM, ZX-I, polyacrylic ester copolymer emulsion, cis-1,4-polybutadiene rubber, styrene-butadiene rubber(SBR), urethane, modification polyureas, low-molecular polyethylene wax or the like;
Water glass: 5%;
Water reducer: 0.3%, this water reducer for example can be sodium lignosulfonate salt water reducer, naphthalene series high-efficiency water-reducing agent, aliphatic high-efficiency water reducing agent, amino high high efficiency water reducing agent, high-efficiency water-reducing agent of poly-carboxylic acid etc.;
Water: 85.4%.
The present invention further discloses the concrete that uses above-mentioned additive to process, this concrete constituent mass is such as down: cement 15%-17%, fine sand 10%, flyash 50%, water 20%, through 1: 35 water-reducible additive 3%-5%.Preferably, working temperature is more than 0 degree.
Cut off the foam concrete block that uses with the production interior wall and be example, it requires dry density to be lower than 800kg/m3, and ultimate compression strength is not less than 3.5Mpa.Its usage ratio is: cement 17%, fine sand 10%, flyash 50%, water 20%, and through 1: 35 water-reducible additive 3%.Making processes is: in the Working environment of 5 degree above freezing, through stirring, cast, moulding, maintenance, cutting, detect later on through natural curing in 28 days, dry density is 786kg/m3, ultimate compression strength 3.6Mpa.
