It has light weight, high strength, low dry shrinkage, high energy saving index, low cost, high durability, high acid and alkali resistance, and other advantages.
Description
(1) technical field
What the present invention relates to is a kind of material of construction, specifically a kind of construction material.
(2) background technology
Building wall material also exists industrial residue building block brick and silicate and aluminosulfate cement wallboard etc. except that clay brick at present.Traditional clay solid brick, because of its serious waste land resources, energy consumption is serious, and serious environment pollution, and Jian Zhu engineering is also not energy-conservation simultaneously, building labour intensity height, building cost is big, and speed is slow, and the building index of realization is on the low side, is forbidden by national explicit order.Other industrial and agricultural waste in addition is that the novel wall material of main raw material all has the corresponding production advantage and building advantage.As sharp useless, environmental protection, less energy-consumption in producing, realize that intensity height on the building function index, freeze-thaw-, weather resistance, impervious, anti-folding and erosion resistance etc. all can realize national new standard-requireds, the novel wall material preferably of can yet be regarded as is worthy to be popularized.But must see that up till now most novel wall materials still have the deficiency and the defective of many aspects, as: the wallboard drying shrinkage value that has is bigger than normal, and the crack was serious when product was installed; The anti-folding of the wallboard that has, index such as freeze proof, corrosion-resistant are not high enough, use range is restricted; The materials for wall that has can not directly reach energy-saving index, need add insulation and handle, and causes building cost to strengthen or the like.
(3) summary of the invention
The object of the present invention is to provide a kind of good performances such as intensity height, impermeability, freeze-thaw-, corrosion-resistant, weather resistance, anti-folding that have, compact structure, drying shrinkage value be lower, can effectively control wallboard installs fissured high strength light wall board material.
The object of the present invention is achieved like this: it is to be consisted of by weight percent: industrial residue powder 50～70%, the plaster of Paris: 5～10%, cement clinker 10～20%, agricultural wastes vegetable fibre powder 5～15%, cracking resistance staple fibre 0.13kg/m
2Wallboard～0.18kg/m
2Wallboard and compound activator 5～10% are made.
The present invention can also comprise some constitutional featuress like this:
1, described industrial residue powder is fineness 650m
2/ kg～950m
2/ kg, Al
2O
3+ SiO
2＞60% powder.
2, described agricultural wastes vegetable fibre powder is that fineness 20 orders are above, the powder of water ratio below 15%.
3, described compound activator is the mixture of alkalimetal oxide, alkalimetal silicate and alkaline carbonate.
4, described compound activator is that alkalimetal oxide, alkalimetal silicate and alkaline carbonate weight ratio are the mixture of 0.5--2.5: 10--18: 5--12.
5, described industrial residue powder is industrial residue slag or flyash dryness powder, or the dryness powder of the mixture of industrial residue slag and flyash arbitrary proportion.
Principal feature of the present invention is:
1, selecting industrial residue slag, flyash powder for use is main raw material: utilize it to contain the characteristics of alumina silicate glass body or this major ingredient of crystal, pass through compound activator, and select for use a small amount of gypsum, cement heat material also to make exciting agent and part gelling component, make it in the hydration reaction process, wherein covalent linkage such as high-polymerization degree Ai-O-Si, Si-O-Si, Ai-O-Ai are because of OH
-Ionization, and complete rupture produce less ionic group or the single ionic group of the polymerization degree, under certain pH value condition, they again with Na
+, Ca
2+Reactive polymeric, form hydrated calcium silicate and aquation calcium aluminosilicate, it has gelling and solidified nature, therefore the silicate polymerization degree that forms is high, compact structure, after the agricultural plants fiber dust combines, just formative tissue compact structure, intensity, anti-folding, erosion resistance are higher than the novel wall material of silicate cement.
2, cement clinker, gypsum: the two not only all is gum material but also the exciting agent that can do industrial waste residue slag, flyash lateral reactivity, so select for use certain consumption as alkali-activator and part bonding component, with the compound activator acting in conjunction, excite the alumina silicate glass body and form new gelling material with it.
3, agricultural wastes vegetable fibre powder: make the light-weight aggregate that wallboard is made, to reduce wallboard weight and cost.When the gelling material hydration reaction and gum material combine closely, fill therebetween.
4, cracking resistance staple fibre: as the wallboard strongthener, require static resistance strong, length 1.5---2.5cm, this length dispersiveness, workability are all better.Combine closely with hydrated product in the production process, increase product strength and toughness greatly.
5, compound activator: the mechanism of action of exciting agent and the constructional feature of slurry
The alumina silicate glass body is being subjected to alkali to do the time spent, OH
-Effect with it, Si

6, the exploitation of compound activator, application
The alkali-activator of slag (flyash) gelling material should comprise alkali metal hydroxide, and alkalimetal silicate and hydrolysis are the salt of alkalescence.Learn that by test their effect differs, single use stimulation effect, excites the time limit all not ideal enough time of coagulation, can not satisfy the needs that production, technological operation and quality product require.How under the first final set condition of realizing ideal, stimulation effect is best again.Excite the time limit optimum, cost is lower relatively again, is the gordian technique that we study selection.
By a large amount of tests, finally we have selected three kinds of alkaline matters as the compound acting in conjunction of exciting agent.Play the synergistic complementary action mutually, thereby realized dreamboat.
Show by a large amount of experiments: excite the time limit longer when independent use oxyhydroxide, stimulation effect is relatively poor, excites the time limit to shorten when adding silicates again, and stimulation effect is better, but the back time limit of condensing is too short.Add carbonate again and come the speed of delayed response, play delayed coagulation, promote stimulation effect more complete simultaneously.We have found best combined formulation by a large amount of tests, have not only realized that ideal excites time limit, first final setting time, but also played abundant excitation, reduces the input cost of exciting agent simultaneously.Finally we have realized, the time of initial set is: 1 hour, final setting time was 1.5 hours, had obtained the ideal materials for wall by low temperature steam-cured (temperature is controlled between 35～80 ℃).
Flyash, the used complex excitation agent prescription of slag are because of its Ca
2+The content difference distinguish to some extent.Flyash Ca
2+Content is on the low side, and lateral reactivity excites ability low, and it is more than 13.5 that the alkali lye pH value during hydration reaction needs greater than slag, and it is high that the amount ratio slag of lime carbonate, cement clinker, gypsum is wanted; And slag pH value about 12 gets final product, and the consumption of lime carbonate, cement clinker, gypsum is less.Steam-cured excitation temperature flyash is also higher, is generally 50～80 ℃, under the slag normal temperature～50 ℃ can reach ideal effect.
The major advantage of product of the present invention is embodied in:
1, in light weight: body of wall only is 1/15 of common brick " a 49 " wall weight, be the new GRC wallboard weight about 1/2, cement steel wire net rack wallboard 1/3, can significantly reduce production material cost, building operation cost and construction cost etc.
2, intensity height, anti-folding, drying shrinkage value are low: wallboard---offscum in alkali hydrated product porosity is low, is about 50% of ordinary Portland cement, and its aperture size is less, compact structure, so ultimate compression strength reaches as high as 65Ma, anti-folding can reach 15.5Mpa, and the drying shrinkage value can reach 0.2.
3, insulate against sound: the material behavior of wallboard, structure design, make the sound insulation index of wallboard surpass national standard, exceed 3～7 points than similar wallboard sound insulation standard.
4, energy-saving index height: need not high-temperature steam curing in the production, effectively reduce production energy consumption, the thermal insulation material of employing can make body of wall reach the energy-conservation requirement more than 65% of country.
5, with low cost: adopt the waste more than 60%, production technique is simple, and cost is very cheap, and every square metre of comprehensive cost is only about 18 yuan.
6, wallboard weather resistance height, stability are by force: the hydrated product solubleness of offscum in alkali cement is low, only is 1/15 of ordinary Portland cement---and 1/25, so the weather resistance of wallboard and stability surpass cement products.
7, high resistance to acids and bases: because of the offscum in alkali hydrated product mainly is low basicity hydrated calcium silicate and float stone class mineral, and porosity is low, (be ordinary Portland cement 50%), its aperture size is also less, compact structure, so embody high resistance to acids and bases, make product both can use the common building engineering, more can be used in the part engineering that cement products do not satisfy.
