Description
(1) technical field
What the present invention relates to is a kind of material of construction, specifically a kind of material of construction that contains cement and organic compound.
(2) background technology
At present, environment is more and more paid attention to protecting in countries in the world, has developed many recovery technologies, industrial waste is applied in the building goes, and promptly the environmental protection and saving energy is created economic benefit, can enrich building material market again.Depleted polystyrene foam (EPS) stable chemical performance, not perishable has produced great pollution to environment.Simultaneously, it is again the good light material of heat-insulating property.The light aggregate concrete that it is made as concrete light skeletal, density is low, thermal conductivity is little, sound insulation, and cost is low.Be used widely abroad,, use the EPS light aggregate concrete except building villa, commercial building etc., application is also arranged in fields such as the backfill of road traffic road surface and levelling, antifreeze roadbeds especially in the U.S. and Canada.Because its density is little, available its built floating marine structure.Domestic, this respect starting is later comparatively speaking, though the EPS light aggregate concrete is had certain research, all is in the research exploratory stage, is not applied, and does not still have clear and definite rules reference.
As the modified EPS light aggregate concrete of novel energy-conserving body of wall main raw, mainly have two kinds of functions: the one, during the concrete placement as the body of wall side form; The 2nd, as wall heat insulation material.As seen, the modified EPS light aggregate concrete not only will have the low performance of thermal conductivity, but also requires material itself to have certain load intensity.And between the selection of the thermal conductivity of this material, load intensity and each raw material, each raw material the proportion relation and the treatment process of part material etc. closely related, these relations are mainly reflected in:
1. the contradictory relation of intensity and volume density
EPS particulate add-on is big more, and the density of modified EPS light aggregate concrete is low more, and cubic compressive strength is also along with decline simultaneously.Improve intensity, volume density increases, and its heat-insulating property can not be guaranteed again.
2.EPS the character characteristics of particle itself have material impact to every performance of modified EPS light aggregate concrete structure:
(1) the EPS granular mass is extremely light, EPS particle come-up (demixing phenomenon) can occur with common stirring and forming method, causes modified EPS light aggregate concrete quality inhomogeneous, reduces its performance greatly.
(2) size of EPS grain diameter and level pairing modified EPS light aggregate concrete pore structure play conclusive effect.In general, the EPS grain diameter is big more, and is single more, and the hole, footpath of modified EPS light aggregate concrete is also big more.Will cause the hole of modified EPS light aggregate concrete more.
(3) because the EPS particle is a kind of organic materials, its surface has lipophilicity, and cement is a kind of inorganic materials, based on ionic compound, its surface-area group has the intensive water-absorbent, and the surface properties of two kinds of completely different materials has caused its surface to be difficult to combination.So, the not firm problem of bonding appears between EPS particle and the sand-cement slurry easily.And material matter is soft and consumption is very big, if the sand-cement slurry consumption is few, just is not enough to wrap up the EPS particle, and this just causes at the very great hole of the inner formation of modified EPS light aggregate concrete.
Do not reach requirement just because of the ultimate compression strength that these issue handlings is got improper, the present concrete material that contains EPS, thermal conductivity etc.
(3) summary of the invention
The object of the present invention is to provide the light energy-saving heat-insulating wall material that a kind of thermal conductivity is little, load intensity is big.
The object of the present invention is achieved like this: it is the light skeletal of 1.2-2.6%, the gelating material of 72-76%, the sand of 22-26% by weight ratio, and accounts for the water of gelating material weight 35-88%, the swelling agent that accounts for gelating material weight 13%, the water reducer that accounts for gelating material weight 1% and make.
The present invention can also comprise some features like this:
1, described light skeletal is a polystyrene.
2, described light skeletal is polystyrene and perlite, and polystyrene and perlitic ratio are 0.8-0.9: 1.
3, described gelating material is a silicate cement.
4, the gelating material of narrating is silicate cement and flyash, and the ratio of silicate cement and flyash is 1: 0.15-0.20.
5, described polystyrene is the mixture of the regenerated polystyrene of 50% primary polystyrene and 50%.
6, the particle radius of described polystyrene is between 1-6mm.
7, described water reducer is lignin sulfonate modified high efficiency water reducing agent.
Product of the present invention can adopt following two kinds of methods to make:
1, at first polystyrene is ground into the particle of radius between 1-6mm with pulverizer, add water make polystyrene become moistening after, adding silicate cement, sand, perlite, flyash, swelling agent stir together, add with remaining water behind the dilute with water water reducer, product is made in stirring, moulding.
2, at first polystyrene is ground into the particle of radius between 1-6mm with pulverizer, with a part of polystyrene and silicate cement blunge, polystyrene is wrapped up by silicate cement, maintenance 24 hours, be that remaining silicate cement, flyash, perlite, sand, water evenly stir together, product is made in moulding.
In product of the present invention, silicate cement, flyash are gelling material, and sand is an aggregate, and granules of polystyrene, perlite are light skeletals, and water is the material that mixes and stirs of mortar.
Silicate cement is to burn to partial melting with the raw material of suitable composition (Wingdale of calcium oxide, silicon oxide, aluminum oxide, ferric oxide, clay and iron powder are formed), the gained Calucium Silicate powder is the Portland clinker of main component, adds the levigate hydraulicity gelling material of making of an amount of gypsum and mixing material.It is a topmost gelling material in the material of the present invention, and its mechanical property is played significant feature.
Flyash is the waste material that emits behind the coal dust firing of fuel-burning power plant, belong to volcano grey matter active addition, its major ingredient is the oxide compound of silicon, aluminium and iron, has the potential chemically reactive, flyash separately and water mix and stir and do not have hydraulically active, but Ca (OH) is being arranged
2Under the condition that exists, can generate with the water reaction and be similar to the gum material of cement gel body, and have certain intensity.Because flyash is trickle, and forms glass microsphere in the high-temp combustion process, so the most globulates of fly ash grain.The flyash particle diameter is many below 45 μ m, can be without grinding directly as concrete adulterant.Have the potential chemically reactive in the flyash, fine particles mixes and can bring into play activity, form, three kinds of effects of particulate in the concrete.Active SiO
2, Al
2O
3, Fe
2O
3The content of isoreactivity material surpasses 70%, although these active ingredients do not possess the hydraulicity separately, separates out Ca (OH) at hydrated cementitious
2After, can react with these active substance generation secondary hydrations, generate gels such as hydrated calcium silicate, hydrated calcium ferrite, have cementing power; Contain a large amount of glass microspheres in the flyash, spherical in shape, mix the internal friction resistance that can reduce concrete mix in the concrete, improve mobile or the minimizing water consumption, improve the workability of mixture; The flyash particle diameter is mostly less than 0.045mm, and especially the one-level ash is also thinner than cement granules generally, so can be filled among the pore and pore of cement gel body, makes the cement gel body more closely knit.
Therefore, flyash is as concrete mineral admixture, existing certain activity effect, be unlikely to make concrete intensity to reduce too much, the workability fine simultaneously, that the spheric particle can improve mixture reduces concrete early water heat-transmission, reduce thermal cracking, and can make sclerosis back concrete more closely knit, improve concrete permeability resistance, improve weather resistance.
Perlite is a kind of acid volcanic rock, mainly is made up of the glassiness, and when the acidic lava ejection face of land, owing to differ greatly with air themperature, magma quenching and have very big viscosity makes not dissipation of energy and being present in the glass physique of a large amount of water vapour.During roasting, perlite heats up suddenly and reaches softening point temperature, the water vapor in the glassiness structure, produce very big pressure, heavy-gravity glassiness volume is expanded rapidly, when being cooled to its softening temperature when following, just congeal into and have that does not wait in the aperture, the cellular material of cavity, i.e. pearlstone.
Expanded perlite granule inside is honeycomb structure, have light weight, insulation, sound absorption, nontoxic, tasteless, do not burn, characteristics such as corrosion-resistant.Except that can be used as the light skeletal of light weight concrete directly as thermal insulation, the sound-absorbing material.General two classes of dividing of pearlstone: particle diameter is called expanded pearlite sand less than 2.50mm's; Particle diameter be 2.50～30.00mm be called the pearlstone rubble, be called " pearlstone " traditionally.The present invention mainly uses the pearlstone of 2.5～4.0mm.
Be divided into ordinary water-reducing agent and high efficiency water reducing agent according to diminishing ability size.The present invention selects lignin sulfonate modified high efficiency water reducing agent, and high efficiency water reducing agent nearly all is a polymer dielectric, and cement granules is had very high dissemination.The organic molecule of water reducer mainly is adsorbed on solid-water termination, and solid particles surface has residual charge usually, may be that positive charge also may be that negative charge or both have.In cement slurry, have opposite charges on the adjacent cement granules, can produce considerable electrostatic attraction, cause particle flocculation, a large amount of water is wrapped in the aggregate and is adsorbed in solid surface, and remaining less water is in order to reduce grout and even concrete viscosity.Can neutralize these surface charges and make all surface all have identical charges of the molecule of water reducer.At this moment, particle repels mutually but not attracts, and is scattered in the grout fully.Therefore, major part can be used for reducing the viscosity of grout.Mix 0.5%～1.5% the water reducer that accounts for cement quality, the flowability of concrete mix is improved greatly.
The function of swelling agent is to make the concrete after the sclerosis produce certain volumetric expansion, the early stage shrinkage crack that produces of deduction and exemption concrete hardening.The UEA swelling agent belongs to calcium sulphoaluminate class swelling agent, and this class swelling agent aquation forms ettringite (C
3A3CaSO
432H
2O) xln, its crystalline growth power can produce volumetric expansion, but main root is that the ettringite surface is electronegative, suction swelling.Offset the concrete dried contraction of moulding by the expansion that this two aspects reason produces.
