Abstract
The invention discloses foamed concrete. The foamed concrete is prepared from the following ingredients in percentage by mass: 25-60% of cement mortar, 5-15% of water, 1-3% of water reducing agent, 1-3% of plasticizer, 1-5% of foamer, 0.1-5% of inorganic salt, 0.5-5% of waterproofing agent, 1-10% of clay, 3-12% of admixture and 5-25% of adjuvants. The foamed concrete disclosed by the invention is mainly used for solving the problem of the current foamed concrete materials that the service life is relatively short due to cracking and water absorption; the plasticizer is epoxidized soybean oil, thereby being more green and environment-friendly; the adjuvants are substances with relatively small grain size, thereby having the advantages of filling gaps of the cement mortar and improving mechanical properties; and a variety of additives cooperate with one another, so that the foamed concrete with excellent crack resistance is obtained.
Description
Technical field
The present invention relates to a kind of structure material, particularly relate to a kind of foamed concrete.
Background technology
Foamed concrete is the novel coagulation fill material grown up for nearly ten years, it is mechanically fully foamed by whipping agent by the foamed system of foaming machine, and foam is mixed with other addition materials are full and uniform according to a certain percentage with grout, then the pumping system through foaming machine carries out cast-in-place construction, through a kind of light-duty filling material containing a large amount of sealed porosity that natural curing is formed.Foamed concrete is owing to having many-sided advantages such as lightweight, intensity is adjustable, height flows, low bullet damping property is good, it is made to have a good application prospect in traffic engineering, as Soft Ground, the backfill of bridge (culvert) back of the body, cold frozen earth roadbed heat-insulation and heat-preservation, platform carry on the back banket anti-freeze expansion and widening of subgrade etc.Solution soft soil base sedimentation, bumping at bridge-head, high roadbed reclamation, widening project, the problem such as to save the area also there is significant advantage.But due to hardened foam concrete surface cracking, cause absorbing a large amount of external moisture, cause reduce work-ing life, have impact on its application.
Because the defect that above-mentioned existing spirochetal casting production process exists, the present inventor is based on being engaged in the practical experience and expertise that this type of product design manufacture enriches for many years, and coordinate the utilization of scientific principle, actively in addition research and innovation, to founding a kind of Novel foam concrete, it is made to have more practicality.Through constantly research, design, and through repeatedly studying sample and after improving, finally creating the present invention had practical value.
Summary of the invention
Main purpose of the present invention is, overcomes the defect that existing foamed concrete exists, and provides a kind of Novel foam concrete, improves resistance to cleavage, reduces water suction, thus is more suitable for practicality, and have the utility value in industry.
The object of the invention to solve the technical problems realizes by the following technical solutions.According to a kind of foamed concrete that the present invention proposes, be made up of each component of following mass ratio, 25 ~ 60% sand-cement slurry, 5 ~ 15% water, 1 ~ 3% water reducer, 1 ~ 3% softening agent, 1 ~ 5% pore forming material, 0.1 ~ 5% inorganic salt, 0.5 ~ 5% water-resisting agent, 1 ~ 10% clay, 3 ~ 12% admixtures and 5 ~ 25% auxiliary material.
Aforesaid foamed concrete, described water reducer is main chain is methacrylic acid, and side chain is the polyester type structure polycarboxylate water-reducer of hydroxy-acid group.
Aforesaid foamed concrete, described softening agent is epoxy soybean oil.
Aforesaid foamed concrete, described pore forming material is any one or any two kinds and two or more mixtures in alkyl sulfonic ester, hydroxyalkyl ether sulphonate, alkyl ether sulfonates, hydroxyalkyl ether sulfuric ester, alpha-olefin sulphonate, benzene sulfonamide acid esters, alkyl sulfuric ester, alkyl ether sulphate, alpha-olefin sulfuric ester, alkylbenzene sulfuric ester.
Aforesaid foamed concrete, described inorganic salt are calcium chloride, calcium formiate, nitrocalcite, calcium stearate, magnesium salts or aluminium salt.
Aforesaid foamed concrete, described water-resisting agent is the one in methyl silicon sodium alcoholate, ethyl sodium silanolate or poly-ethyl hydroxy siloxanes.
Aforesaid foamed concrete, described admixture is prestox polyhedral oligomeric silsesquioxane and glass fibre.
Aforesaid foamed concrete, described auxiliary material is silicon ash, calcium carbonate, slag, flyash, volcanic ash, limestone powder, ureaformal dehyde resin glue, SILICA FUME or their mixture.
By technique scheme, foamed concrete of the present invention at least has following advantages:
The problem that foamed concrete of the present invention is mainly used in solving cracking that current foamed concrete material exists, the work-ing life of causing of absorbing water is shorter, wherein softening agent adopts epoxy soybean oil environmental protection more, the material that auxiliary material adopts particle diameter smaller, has filling concrete mortar gap, improves the advantage of mechanical property; Prestox polyhedral oligomeric silsesquioxane in admixture and glass fibre are worked in coordination, wherein chopped E-glass fiber surface has more amino, react with the prestox polyhedral oligomeric silsesquioxane (poss) containing epoxy group(ing), nano level POSS well and glass fibre there is embedding company, the surface of the chopped E-glass fiber of thick line structure wraps by the prestox polyhedral oligomeric silsesquioxane being equivalent to have dots structure; Poss surface inertness group and polyvinyl chloride (PVC) RESINS (fine rule structure) have good consistency, and in polyvinyl chloride, have good dispersiveness, poss is connected in polyvinyl chloride (PVC) RESINS organic chain in the mode of chemical bonding; Therefore, prestox polyhedral oligomeric silsesquioxane plays good function served as bridge between chopped E-glass fiber and polyvinyl chloride (PVC) RESINS, and then improve the physical strength of glass fiber material, the effect playing cracking resistance that can be higher, and then reduce material cracks and to absorb water the lost of life caused.Multiple additives is worked in coordination and is obtained the excellent foamed concrete of resistance to cleavage.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technique means of the present invention, and can be implemented according to the content of specification sheets, be described in detail as follows below with preferred embodiment of the present invention.
