Abstract
The building material is produced with flyash as main raw material and pearlite, magnesia powder and magnesium chloride solution as supplementary material and through a no-baking and no-steaming process. It may be used in producing bearing and non-bearing wall brick, heat-insulating roofing plate and plastering powder, and it has great flyash content, low cost and high strength.
Description
The present invention relates to a kind of material of construction, specifically a kind of flyash-containing building material of free of calcining and steam curing.
The big or small heat power plant and other consumption coal enterprises that spread all over China various places, the a large amount of flyash of annual generation, add and over the years in time handle, environment has been caused serious day by day harm, and increasing ash discharge amount, also caused huge economical load to enterprise, develop the big product of a kind of flyash consumption, flyash is turned waste into wealth, obtain sufficient second stage employ, alleviate the heavy burden of ash discharge enterprise, reduce production cost with grey enterprise, more can significantly reduce pollution level to environment, in recent years, some have appearred in China is the material of construction of raw material with flyash, as Chinese patent " non-fired and non-steamed bricks and preparation method thereof the " (patent No. 89109385.0, the applying date 891216), this invention is by flyash, cinder (or clay), cement, lime, admixture is formed, the flyash content of this invention reaches 20-65%, it is big to eat the ash amount, free of calcining and steam curing and is compared with the flyash brick of roasting through steam-cured, and the tool facility investment is few, easily make, the advantage that cost is low, but on the make, the auxiliary material cinder must make it particle diameter less than 6mm through fragmentation before using, and lime requires also higher, mistake flint in the lime can not be too much, effectively calcium chloride content is greater than 65%, and must be through levigate (4900 hole sizers are not more than 15%), so manufacture craft is still complicated before using, and the kind of auxiliary material is also more in the raw material, and curing time also reaches 28 days; And for example applied for " the flyash of Chinese patent, pearlstone system lagging material " (application number 93105850.3, the applying date 930527), this lagging material is a kind of light building material that is used for aspect insulation and non-load bearing wall, it is to be agglutinate with the magnesium cement, adding flyash and pearlstone makes, pre-treatment and cladding process have been adopted in the technological process, this invention tool is non-evaporating, unburned, energy-conservation profit is useless, good waterproof performance, the advantage that intensity improves, but flyash content is the highest has only 34% for it, the agglutinate that face is formed with magnesium cement and additive is but up to 25%-54%, and agglutinate is by magnesia, MgCl
2(solid), polyvinyl alcohol material, hemp cut, waterproof material are formed, and raw material type is more, makes it complex manufacturing process, and the cost increase, and raw material variety is many more, and it is also bigger influenced by the market factor; And for example " insulating brick and making method " (application number 94100099.0, applying date 940112), this invention proportioning raw materials (in weight %) is flyash 50-58%, pearlstone 25-35%, waste polyethylene foam materials flour 3-10%, cement 5015%, this invention flyash content is up to 50-58%, big with the ash amount, and free of calcining and steam curing, but it must add 5-15% cement, and perlite content is also bigger, cost is higher, and ultimate compression strength only is 0.4MPa/cm
2More than, flyash content is at " lay bricks thermal insulation mortar powder and production method thereof " (application number 94100097, the notification number 110548) in addition more than 50%, and this product is measured up to 78% with ash, but it can only be plastered a wall as laying bricks.In sum, existing powdered coal ash products as building material generally uses cement to be jointing compound, and feed composition is mostly more than six kinds, and technology is complicated, and curing time is long, and purposes is also limited, and is general only as the non-bearing material.
It is very simple that purpose of the present invention aims to provide a kind of manufacture craft, and raw material type is few, without cement, free of calcining and steam curing, " eating " ash amount greatly, and intensity height, the flyash-containing building material that purposes is wide.
The objective of the invention is to realize in the following manner: a kind of flyash-containing building material, form by flyash, perlite, magnesia and magnesium chloride solution, its proportioning raw materials (% meter by weight) is: flyash 50-70%, perlite 5-20%, magnesia 10-30%, magnesium chloride solution (proportion 2.5) 15-16%.
Flyash, perlite, the magnesia of said ratio are mixed, adding magnesium chloride solution stirs, stirred 2-3 hour, become thick shape, in closed unit, vacuumize then, send into extrusion molding in the shaper again, or make brick, or make plate, unburned, non-evaporating, natural curing can be used after 24 hours.
The present invention has following advantage:
1, " eat " the ash amount greatly, with low cost without cement, the economic benefit height, environmental.
With green hill, Wuhan heat power plant is example, about 700,000 tons of annual ash discharge, to pay 5 yuan for one ton, amount to 3,500,000 yuan of ash discharge expenses, if the producer to production powdered coal ash product of the present invention provides free flyash, the annual expense that can save 3,500,000 yuan, and with the spending that this main raw material of flyash can be saved in ash side, reduce cost greatly; Perhaps power plant oneself builds a fly-ash building-material factory, has then not only saved the ash discharge expense, and has turned waste into wealth, and creates more economic worths, in time handles flyash, has also reduced environmental pollution, also can solve rich labor force's problem simultaneously.
2, purposes is wide, and this material can be used for load-bearing or furring tile, roof lightweight thermal baffle, the ash of plastering a wall of laying bricks.
3, free of calcining and steam curing, curing time is short, save energy, the input of saving fixture.
4, intensity height is an example with the heavy-load bearing brick of making, and detects and does content 700-1100kg/m
3, average intensity R 〉=4MPa.
5, can follow closely, can saw, it is very convenient to construct.
Embodiment 1: 500kg flyash, 150kg perlite, 200kg magnesia are mixed, add proportion 2.5 magnesium chloride (MgCl
2) solution 160kg stirred 3 hours, sent in the encloses container to vacuumize, and put into brick extruding machine then and was squeezed into brick, can harden in 2-3 hour, natural curing got final product in 24 hours.
Embodiment 2: 550kg flyash, 200kg perlite, 100kg magnesia are mixed, add the 150kg magnesium chloride solution and stirred 3 hours, inject encloses container and vacuumize, send in the making sheet mould, free of calcining and steam curing makes lightweight thermal baffle.
Embodiment 3:700kg flyash, 50kg perlite, 100kg magnesia mix, and add the 150kg magnesium chloride solution and mix stirring 2 hours, can lay bricks and plaster a wall.
