Regenerated baking-free archaized black brick and manufacturing method thereof

Abstract

The invention discloses a regenerated baking-free archaized black brick and a manufacturing method thereof. The regenerated baking-free archaized black brick comprises the following raw materials in percentage by weight: 7-12% of 42.5 MPa-grade ordinary portland cement, 0-10% of II-grade fly ash, 75-80% of waste concrete blocks with the size of 0-10mm, a proper amount of pigment and a proper amount of water. The method comprises the steps of adding the waste concrete blocks and the II-grade fly ash according to a ratio, then adding a green pigment, adding a small amount of a blue pigment for multiple times, conducting stirring, adjusting the designed color, and then manufacturing the regenerated baking-free archaized black brick by using a brick machine through an excitation molding process. According to the invention, the waste concrete blocks are selected as the main material for manufacturing the regenerated baking-free archaized black brick, the colors of the waste concrete blocksand the regenerated baking-free archaized black brick are close, wastes are utilized, and lots of land resources are saved; a proper amount of II-grade fly ash is added, so that the porosity of the brick body can be reduced, and the compactness and 28-day compressive strength of the brick body are improved; the mixing amounts of the two pigments are determined by regulating, so that the brick bodycan be effectively ensured to reach the designed color; and According to the manufacturing process, the defect of CO2 gas emission caused by a firing process is avoided, a large amount of energy is saved, and the ecological environment is improved.

Description

technical field [0001] The invention relates to a regenerated unfired antique green brick and a manufacturing method thereof, in particular to a regenerated unfired antique green brick and a manufacturing method thereof. Background technique [0002] At present, the main raw material for making antique blue bricks is clay. After the clay is mixed with water, it is extruded, then baked in a brick kiln to about 1000 degrees, and cooled with water, so that the iron in the clay is not completely oxidized, so that it has better anti-oxidation and humidity regulation (the pores distributed in the brick can absorb and discharge the outside world. The brick body releases moisture during the day and absorbs moisture at night), non-slip, environmentally friendly (no radioactivity), low water absorption, good frost resistance, and no deformation. After testing, the anti-compression of ancient green bricks is greater than 10 MPa, and the water absorption rate is less than 20%. [0003...

AI Technical Summary

Problems solved by technology

[0004] However, the production of antique blue bricks wastes a lot of land resources, and at the same time releases a large amount of CO2 gas during the firing process, which seriously affects the ecological environment.

In addition, a large amount of energy is consumed in the firing process, which is not in line with my country's energy conservation and emission reduction guidelines, and is not conducive to the long-term development of enterprises.
