FIRED BRICK WITH HIGH CONTENT OF RECLAIMED ANTHRACITE COAL ASH AND PREPARATION METHOD THEREOF

摘要

The present invention replaces 30 ~ 90wt% of the natural raw materials used in the manufacture of calcined bricks with anthracite coal ash and fly ash, thereby reducing the cost and strength characteristics of calcined bricks, as well as recycling the landfill ash and fly ash, and using natural resources. The present invention relates to an anthracite embedded coal ash-containing calcined brick and a method for manufacturing the same, which can achieve protection of the natural environment due to reduction. The main configuration of the present invention is a method for producing the anthracite-coated coal ash-containing calcined brick is a step of preparing anthracite coal ash mix soil by mixing 20 to 80wt% landfill ash, 10-40wt% fly ash, 10-70wt% feldspar; Mixing the blended raw materials by kneading 3 to 4 times in a clay process for aging for 130 to 150 hours, and then molding the blended raw materials by vacuum extrusion; The molded brick is characterized in that the firing is maintained for 1 to 4 hours after the temperature is raised to a temperature range of 1000 ~ 1250 ℃ in a tunnel type kiln.;    Fired brick, anthracite, anthracite landfill coal ash, landfill ash, anthracite coal ash, fly ash, bottom ash, kaolin, vacuum extrusion molding
