Abstract
The invention belongs to the non-burning brick and production method of a kind of waste residue.Feature is that its component comprises the sulfate cinder of 60-80% (weight), the water glass of the calcium carbide cream and 0.2-2% (weight) of 18-40% (weight).With said components mixing in proportion, moulding, natural curing 14-28 days, the non-burning brick common building brick 100 that meets that makes
#Standard.The present invention not only can produce the Highrise buildings brick, but also production walkway standard paving brick.The present invention has found a valid approach for a large amount of utilizations of sulfate cinder.
Description
The present invention relates to a kind of building brick, specifically belong to a kind of waste residue that utilizes and produce non-burning brick technology.
Traditional composition brick is a clay brick, and this brick not only uses clay in a large number, occupy cultivated land, and vegetation destruction, and need sintering, consume the energy.For addressing the above problem, utilize slag in recent years, the technology of making burn-free bricks such as slag at home and abroad develops soon, also has many patents to come out one after another, and discloses a kind ofly by sand, slag, cement as CN86103104A, and calcium oxide is made non-burning brick technology.It does not ruin the arable land without clay, without sintering, saves the energy, utilizes waste residue, decontamination, and still, this brick will add the cement of 12-32% in process of production, is a kind of cement products in fact, and the brick cost height that causes has limited promoting the use of of it.
The purpose of this invention is to provide a kind of waste residue that utilizes, do not use cement, cost is low, the non-burning brick and production method that quality product is high.
Provided by the present invention non-burning brick, be characterised in that the component of this brick comprises 60-80%(weight) sulfate cinder, 18-40%(weight) calcium carbide cream and 0.2-2%(weight) water glass.
Described sulfate cinder is the waste residue that sulfuric acid industry is produced, and is that vitriol works wants to handle and the difficult problem that can't handle for a long time.The major ingredient of this slag is Fe
2O
3, SiO
2, Al
2O
3Deng.Because the ferric oxide proportion is bigger in its component,, only is suitable for and makes the walkway floor tile so directly the non-burning brick unit weight with the sulfate cinder preparation is big.As produce the Highrise buildings brick, sulfate cinder must be got rid of ferric oxide major part wherein through magnetic separation or gravity treatment, reduces the unit weight of brick.Also can use the flyash instead of part sulfate cinder in fuel-burning power plant simultaneously, so also can reduce the unit weight of brick, can change the color of sulfate cinder, make the more approaching common grey brick of non-burning brick color of production.
Described water glass is adhesiving reinforcing agent, adds less water glass in component, can effectively improve the intensity of brick.
Also can add a spot of industrial sulphuric acid in addition in component, be generally the 0.1-1% of total component weight, it has the pectisation of exciting, and can make fragment of brick accelerate gelation rate.
Non-burning brick production method provided by the present invention, feature is that sulfate cinder (is needed earlier through deironing as the common building brick, the ground paving brick needn't deironing) be crushed to below 3 millimeters, add together by above-mentioned non-burning brick component and content thereof then, mixing, and add and to be enough to the water that makes the said mixture material moistening, press and ground 5-15 minute, compression moulding, natural curing 14-28 days.In earlier stage need be topped in natural curing, in case appearance rapid drying causes the decortication phenomenon.
Compared with prior art the present invention has following characteristics: the first, but the present invention utilizes both production ground bricks of sulfate cinder, can produce the Highrise buildings brick again, for an effective way has been found in a large amount of utilizations of waste residue of sulfuric acid.The second, without cement, cost is low in the present invention's batching, and the brick quality of producing all meets the related standards of country to common building brick and walkway " concrete road pavement brick ".
