Description

Building material of volcanic ash for large wall
The invention belongs to large-scale wall body building material field.
The large-scale building wall that past people is produced mostly is silicate cement mud product, chloro-magnesium cement goods (being magnesite product), vitriol plastering, and artificial marble plate with plate, building block.These wall body building materials exist to some extent than great, yielding shortcoming such as get damp.CN1053049A disclosure of the Invention specification sheets proposed a kind of with viscosity sand as base material, mix waste residue by a certain percentage, a small amount of cement, trace mineral supplement (volcano float stone, soap powder, salt, molasses non-burning brick, this brick belongs to small-sized standard red soil cob brick series, with the green grass or young crops of firing, and the common brick ratio, certain advantage is arranged, but be unsuitable for doing large-scale wall body building material.Silicate building products 81[2] on delivered one piece and be entitled as the article of " utilizing volcanic tuff to produce steam-cured artificial light aggregate ", speak of volcanic tuff with 0.9mm after fragmentation and blast-furnace slag, slaked limes etc. are mixed and made into the artificial light aggregate, and then be used to mix the system concrete, the artificial light aggregate intensity that makes with this method is improved, but complex process, the cost height, concrete adulterant only suits to be used as.
The objective of the invention is in order to overcome the deficiencies in the prior art, proposing a kind of is lightweight, waterproof, fire-resistant, the large-scale wall body building material of main base material with volcanic ash, and not only technology is simply with low cost for it, and resourceful volcanic ash is fully used.
The present invention realizes like this.Volcanic ash wall body building material of the present invention comprises light-weight hollow building block made, the light foam wall body brick, light sheet, by volcanic ash, cement (or chloro-magnesium cement), gypsum (or slaked lime), additive (aluminium powder, hydrogen peroxide, trolamine, sodium hydroxide, sodium-chlor) clear water (or magnesium chloride brine) mixes composition, their weight percent is: volcanic ash 55～90%, cement 5～40%, gypsum 4～5%, additive 1～2%, water cement ratio 0.2～0.5.Wherein, the optimum weight per-cent of light-weight hollow building block made is: volcanic ash 80～90%, Portland cement 5～16%, terra alba 4～5%, water cement ratio 0.3～0.4.The optimum weight per-cent of light foam wall body brick is: (one) volcanic ash 60～80%, cement 12～20%, gypsum 3～4%, additive 1～2%, water cement ratio 0.3～0.5; (2) volcanic ash 60%, chloro-magnesium cement 35%, 15～20 ° of magnesium chloride brine concentration, gypsum 3～4%, additive 1～2%.The optimum weight per-cent of light sheet is: volcanic ash 55～70%, chloro-magnesium cement (magnesia powder) 25～40%, 20～25 ° of magnesium chloride brine concentration, glass fibre or rock wool 3～4%, additive 1～2%.With natural curing behind the above-mentioned materials difference mixing moulding 7～28 days, both can get finished product.
Mechanism of the present invention is: pozzuolanic chemical ingredients mainly contains SiO 2, inferior is Al 2O 3, these acidic oxides have activity, energy and Ca(OH) 2React with generates stable water-soluble moisture Calucium Silicate powder (XCaOSiO at normal temperatures and pressures 2NH 2O) and moisture calcium aluminate (YCaOAl 2O 3NH 2O).These aquo compounds can harden in air, and continue sclerosis in water, thereby produce intensity, but volcanic ash can not be more than 90%, otherwise intensity will be difficult to reach the load-bearing of body of wall requirement, and volcanic ash is less than 55% certainly will increase cement, the proportion of lime does not reach and makes full use of pozzuolanic purpose.Additive aluminium powder of the present invention, hydrogen peroxide, trolamine, sodium-chlor, alkali all are conventional additives, and the adding certain amount of foaming agent, as hydrogen peroxide, aluminium powder etc. then is unstable and the strong oxidizing property of utilizing it, the carbon reaction that contains in oxygen of emitting and the volcanic ash generates carbon dioxide, thereby play foaming effect, be heavier than air owing to carbon dioxide again, thereby form closed little cavity easily, make the goods light weight, sound insulation, heat insulation.Add a small amount of glass fibre or rock wool and then be toughness and bonding force in order to increase light sheet.
Embodiments of the invention are as follows:
Example 1. is produced holllow building blocks: volcanic ash consumption 90%, granularity＜15 millimeter, Portland cement 6%, terra alba 4%(or slaked lime 4%), water cement ratio 0.3, (can according to the formability adjustment).Homogenize adds water and stirs, adopts block machine vibrations compression moulding, natural curing 7～28 days.By standard block (390 * 190 * 190) unit weight 700～800(Kg/m 3), intensity can satisfy the non-load bearing wall requirement.Weight is conventional uses cement, stone, and sand, the holllow building block of clear water stirring pressing and moulding is light by about 30%.
Example 2. is produced the light foam wall body brick
A, volcanic ash 70%, granularity 180～320 orders, cement 20%, gypsum 3%, slaked lime 5%, whipping agent 1%, water cement ratio 0.5;
B. volcanic ash 65%, chloro-magnesium cement (magnesia powder) 30%, gypsum 3%, 15 ° of magnesium chloride brines, the trolamine trace, whipping agent, hardening accelerator 1%, water cement ratio 0.5 mixes homogenize, stir the cast vibrating forming, the demoulding in 7～14 hours, natural curing 7～28 days, intensity can satisfy the requirement of non-bearing infilled wall, and proportion is lighter than water.Specification can be according to national standard or customer requirements.
Example 3. is produced light sheet
Volcanic ash 57%, granularity 180～320 orders, chloro-magnesium cement (magnesia powder) 40%, 25 ° of magnesium chloride brine concentration, glass fibre or rock wool 3%, the trolamine trace mixes homogenize, stirs casting, the demoulding in 7～14 hours, natural curing 7～28 days, specification can be according to national standard or customer requirements, for example 1200 * 600 * 7mm.On thin plate, spray porcelain-imitated coating, also can make the dalle product.
The present invention compares with existing large-scale body of wall construction material and has the following advantages:
1. volcanic ash is done the base material aboundresources, can gather materials on the spot;
2. the invention belongs to the composite that magnesia alumino-silicate is inorganic mineral, have waterproof, fire-resistant, the characteristics of light weight, intensity height, sound insulation, heat insulation and good processability;
3. therefore light weight of the present invention can alleviate the house load-bearing, increases usable floor area and reduces cost of a building;
4. product forming process of the present invention is simple, and unburned, has both saved the energy, and is free from environmental pollution again, can be made into various light building materials, cost is low, purposes is wide, market capacity is big.
