For solving above-mentioned first technical problem, technical scheme of the present invention is:
A kind of autoclaved fly ash brick for construction, make by following materials of weight proportions:
Boiler slag: flyash: Mi Shi: carbide slag: stone flour=13～17: 13～17: 8～12: 18～22: 38～42.
Preferably, described flyash brick is made by the raw material of following weight ratio: boiler slag: flyash: Mi Shi: carbide slag: stone flour=15: 15: 10: 20: 40.
For solving above-mentioned second technical problem, technical scheme of the present invention is:
A kind of preparation method of autoclaved fly ash brick for construction, with powdered boiler slag, flyash, Mi Shi, carbide slag and stone flour by 13～17: 13～17: 8～12: 18～22: 38～42 weight proportion mixes, add entry and make the mixture of water ratio at 10～15wt%, with described mixture compression moulding after steam press maintenance is made finished product.
As a kind of improvement, earlier with rice material stone, carbide slag and stone flour by 8～12: 18～22: 38～42 weight proportion mixes, make compound, described compound was placed 36～72 hours, and then described compound and powdered boiler slag and flyash by 64～76: 13～17: 13～17 weight proportion mixes, and adds entry and makes the mixture of water ratio at 10～15wt%.
Preferably, earlier rice material stone, carbide slag and the stone flour weight proportion by 10: 20: 40 is mixed, make compound, described compound was placed 36～72 hours, and then described compound and powdered boiler slag and the flyash weight proportion by 70: 15: 15 mixed, add entry and make the mixture that water ratio is 12wt%.
Wherein, described steam press maintenance comprises and vacuumizes, intensification, constant temperature, leads vapour and steps of exhausting; Vacuum tightness during described vacuumizing is-0.05MPa; Feed saturation steam during described intensification, 2～3 hours heating-up times, pressure is 0.95MPa; Described constant temperature time 3～5 hours, pressure 0.95MPa.
Owing to adopted technique scheme, the invention has the beneficial effects as follows:
1, the inventor is through testing and verification in many ways, worked out and used the unslaked lime that uses in the existing fine coal brickwork skill of the replacing carbide slag prescription, and add the production technique prescription of Mi Shi, stone flour, adopt steaming pressuring curing process, not only prescription is simple, technological operation is more prone to control with respect to the prior art of using unslaked lime, and the flyash brick steady quality produced of the present invention, on every index all apparently higher than the like product level of national regulation.
2, the present invention uses trade waste flyash and boiler slag to be main raw material, has not only handled the part industrial solid castoff, turns waste into wealth, but also has saved the farmland resource, has protected ecotope, is a kind of novel process of energy-conserving and environment-protective.
