Abstract
This invention relates to a method for producing a construction material, which is composed of: fly ashes 35-40%, shale 30-35%, quicklime 20-25%, and coal 4-7%. The construction material saves waste resources, and is environmentally friendly. Bricks calcined from the construction material and cooled are loose and easy to pulverize, and have higher grindability (increased by 20-30%). The cost is 25-30 yen/ton lower than that of ordinary cement. Concrete produced from the construction material has higher strength and doping resistance than common Portland cement. Volcanic ash Portland cement with various strength grades can be obtained via regulating the doping amount of the construction material. The method is suitable for waste disposal of building material plants and chemical plants.
Description
The present invention relates to a kind of production method of material of construction.
In the industrial production, the unslaked lime slag of discharging in powdered coal cinder that heat power plant discharges and chemical plant and the lime production industry is the big public hazards of two in the environmental improvement.
The flyash and the lime mud that the objective of the invention is to utilize local heat power plant, chemical plant to discharge are produced cement mixture, both administer, environment purification, turn waste into wealth again, produce material of construction inexpensive, of fine quality.
The object of the present invention is achieved like this:
With the method for industrial residue producing cement blended material, the component of material is: flyash 35-40%, shale 30-35%, unslaked lime 20-25%, coal 4-7%.Production process is: (1) preparation blended material, unslaked lime, shale, coal are mixed in proportion, and after grinding and processing, in importing stirrer, flyash stirs, and water ratio reaches 8-12%, is transported to slaking silos again and clears up more than 3 hours; (2) the blended material water mixing is stirred once more, water ratio reaches 18-25%, is pressed into adobe with brick pressing machine; (3) adobe is packed in the kiln, oven dry below first 300-400 ℃ 12 hours, calcining 24 hours under 800 ℃ of-950 ℃ of temperature condition again, natural temperature cooling 1-2 hour down promptly makes high activated admixture; (4) the broken processing of the high activated admixture that makes back is mixed with the cement clinker of 50-65% send into the grinding machine material of claying into power.
The present invention has made full use of the flyash and the lime mud of local heat power plant, chemical plant discharge and has produced cement mixture, administers, purified environment when turning waste into wealth again; Brick after the calcining, quality is loose after the cooling, and broken easily, grindability is good, and mill output can improve 20-30%, saves energy, than the ton cost reduction 25-30 unit of Portland cement; Same proportioning, the same terms be the concrete of preparation down, and its intensity and anti-mixing property are better than ordinary Portland cement; Change its volume, can produce the portland-pozzolan cement of multiple strength grade, the controlling waste residue environmental applications is handled in suitable Building Materials Factory and heat power plant and chemical plant.
The present invention further describes below with reference to embodiment:
Embodiment: 5 tons in the flyash that heat-obtaining power plant discharges, 4 tons in shale, 3 tons of unslaked limes, coal 800Kg, with unslaked lime, shale, coal mix send into the pulverizer grinding and processing after, be transported to the flyash of being got and stir in the stirrer, mix water during stirring, control its water ratio and reach 8-12%, be transported to slaking silos after stirring and cleared up 3-4 hour, make blended material.Blended material is mixed clear water stir once more, control its water ratio and reach 18-25%, be pressed into adobe with brick pressing machine.Adobe is imported in the kiln (tunnel furnace, annular kiln), dried 12 hours down for 300 ℃-400 ℃ earlier, spread 2% coal burning at the outside surface of adobe, 800 ℃ of-950 ℃ of temperature condition were calcined 24 hours down, take out of outside the kiln, naturally cooling 1-2 hour, promptly make high activated admixture.The broken processing of the high activated admixture that makes back mixed with the cement clinker of 50-65% send into the grinding machine material of claying into power.Volume is when 35% left and right sides, and the cement of producing is identical with the portland-pozzolan cement of 42.5 strength grades.Volume is when 50% left and right sides, and the cement of producing is identical with the portland-pozzolan cement of 32.5 strength grades.GB/T17671 detects according to GB, and pack is standby after the acceptance(check).
Claims (2)
