Embodiment Construction

[0015] The blue imitation brick is composed of upper and lower layers, wherein the lower layer is formed by mixing and pressing cement, sand, black powder and water, and the upper layer is formed by mixing and pressing cement, sand, stone powder and adding water.

[0016] The specific production process of the imitation blue brick is as follows: firstly, the mold is filled with a mixture of cement, sand, black powder and water, and the lower layer of the imitation green brick is formed by wet pressing in layers and batches; then the lower layer is filled with cement, sand, and stone powder The mixture with water is wet-pressed in layers and batches to form the upper layer of the imitation blue brick; secondly, after demoulding, it is cured in a steam drying room for 24 hours; finally, it enters the site for natural curing.

[0017] The 24-hour curing temperature in the steam drying room is 20 degrees Celsius, the humidity is 90 degrees, and the natural curing time of the site i...

Abstract

The invention discloses a simulated grey brick which is composed of an upper layer and a lower layer, wherein the lower layer is prepared by mixing and pressing cement, sand, black powder and water; and the upper layer is prepared by mixing and pressing cement, sand, rock powder and water. The simulated grey brick uses local materials, and utilizes the rock powder instead of the black powder, thereby better utilizing the waste materials, lowering the production cost, reducing the damage to the environment, and enhancing the competitive power of the product.

Description

technical field [0001] The invention relates to imitation blue bricks. Background technique [0002] Traditional blue bricks are fired bricks, which are shaped by hand, and the bricks are dried and fired in earthen kilns. The main raw material of ancient blue bricks is clay. After the clay is mixed with water, it is extruded and shaped, and then baked in a brick kiln until it is cooled by water (about 1000 degrees), so that the iron in the clay is not completely oxidized, so that it has better weather resistance and water resistance. and other characteristics. [0003] The hardness of blue bricks and red bricks is almost the same, but the cooling method is different after firing, while the red bricks are naturally cooled, which is simpler. Trouble, so now the production is relatively small. Although the strength and hardness are similar, the performance of blue bricks in anti-oxidation, hydration, atmospheric erosion, etc. is significantly better than red bricks. It is us...
