Embodiment Construction

[0017] The imitation blue brick is composed of upper and lower layers, the lower layer is made of cement, sand, black powder and water mixed and pressed, and the upper layer is made of cement, sand, stone powder and water mixed and pressed.

[0018] 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 blue brick is wet-pressed in layers and batches; then the lower layer is filled with cement, sand, and stone powder. The upper layer of the imitation blue brick is wet-pressed in layers and batches with the mixture with water; secondly, after demoulding, it is cured in a steam drying room for 24 hours; finally, it enters the site for natural curing.

[0019] 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 is 15 days.

[0020] The imitation bl...

Abstract

The invention discloses a production technique of a simulated grey brick. The simulated grey brick 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 production technique comprises the following steps: filling a mixture of cement, sand, black powder and water into a mold, and forming the lower layer of the simulated grey brick in a layer-by-layer wet pressing mode in batches; filling a mixture of cement, sand, rock powder and water into the lower layer, and forming the upper layer of the simulated grey brick in a layer-by-layer wet pressing mode in batches; demolding, and curing in a steam drying chamber for 24 hours; and finally, naturally curing in a place. The technique 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 a production process of imitation blue bricks. Background technique [0002] Traditional blue bricks are sintered bricks, which are formed by hand. The main raw material of ancient blue bricks is clay. After the clay is mixed with water, it is extruded and molded, and then baked in a brick kiln until it is cooled with water (about 1000 degrees), so that the iron in the clay is not completely oxidized, making it more resistant to weathering and water. and other characteristics. [0003] The hardness of green bricks and red bricks is similar, but the cooling method after firing is different, while red bricks are naturally cooled, which is simpler, and blue bricks are cooled by water (actually a kind of oxygen-deficient cooling), which is relatively easy to operate. Trouble, so less production is now. Although the strength and hardness are similar, the performance of blue bricks is obviously better than that of red bricks in te...
