Abstract
The invention relates to a novel wall material, specifically to a cement autoclaved brick and a production method thereof. The cement autoclaved brick is composed of cement, sand, granulated blast furnace slag, fly ash and water. According to the invention, cement is used as a main calcium material and has the characteristics of rapid hardening performance, resistance to sulfate, hydration thermal expansion performance and high temperature resistance; compared with a standard autoclaved brick using lime which has the disadvantages of great hydration heat during hydration, slow hardening, low strength after hardening and poor water resistance, the cement autoclaved brick provided by the invention has better frost resistance, corrosion resistance, compressive strength and the like than the traditional bricks; and as the granulated blast furnace slag is used as a production raw material, the problem of difficult treatment of granulated blast furnace slag in the mining industry can be effectively overcome and production cost of enterprises can be reduced.

Another object of the present invention is to provide a kind of production method of cement autoclaved brick, comprises the steps:
(1) dryly to stir: by material in proportion proportioning then stir;
(2) digest: the compound after stirring is transported to slaking silos and digests;
(3) rolling: adopt wheel roller rolling 3 ~ 5min, control water content to 7 ~ 8% of compound simultaneously;
(4) shaping: the compound after rolling is transported to brick pressing machine hopper, compression moulding;
(5) maintenance: shaping adobe is sent in precuring and carried out maintenance, and the free water in adobe is sloughed gradually;
(6) steam pressure: base substrate is sent in autoclave carry out vacuumizing, heat up, constant temperature and cooling process get product, described vacuumizing is to vacuumizing 0.5 hour in autoclave, make autoclave internal pressure for-0.06MPa, described intensification is that steam pressure temperature in the kettle is risen to 200 DEG C, pressure is-0.06MP ~-1.2MPa, described constant temperature is the condition steam pressure 6 ~ 7h maintaining pressure-1.2MPa, temperature 200 DEG C, and described cooling is that the speed that steam pressure temperature in the kettle is no more than 10 DEG C by 30min cooling is down to Room pressure.
Further, in described step (2), digestion time is 1.5 ~ 2 hours.
Advantageous Effects of the present invention is:
(1) the present invention mainly uses cement as calcareous material, cement has rigid, sulfate resistance, hydration heat swelling property and high thermal resistance soon, comparatively use lime autoclaved standard bricks, when lime has an aquation large, the sclerosis of hydration heat slowly, the defect of low, the poor water resistance of intensity after sclerosis, and the frost resistance of cement autoclaved brick, solidity to corrosion, ultimate compression strength etc. are all better than traditional brick.
