Detailed explanation of the production process of cement bricks

Cement bricks are one of the most important building materials and have a wide range of uses. Cement bricks can be used in various parts of buildings, such as exterior walls, interior walls, floors, ceilings, and roads, bridges, and other public facilities. This article will introduce the production process of cement bricks in detail.

1. Preparation of raw materials

The main raw materials for making cement bricks are cement and sand. There are many types of cement, and the commonly used ones are silicate cement and fast-hardening cement with a fast hardening speed. Sand needs to be screened, cleaned, and dried. In general, adding a certain amount of waste such as coal slag, slag, and ash to sand can increase the density of the brick blank and reduce the production cost.

2. Preparation for making brick blanks

Molds are required to make brick blanks. The mold requires a smooth and flat interior and a firm structure. The materials for making the mold can be steel plates, cast iron plates, wooden boards, etc. Before using the mold, apply a layer of anti-stick coating to prevent the cement bricks from sticking to the mold during the drying process.

3. Production and production

1. Ingredients

First, put the raw materials such as cement and sand into the mixing bucket accurately according to the ratio and mix them thoroughly. Adequate mixing can make the raw materials mix evenly and avoid making bricks of uneven quality.

2. Pressing

The mixed raw materials will be sent to the press through the conveyor belt, and then pressed into shape on the press. During the pressing process, attention should be paid to strengthening the pressing force to ensure the firmness and density of the brick.

3. Spreading ash and sand

After the brick is made, a layer of ash and sand should be spread on the bottom and sides of the brick. This layer of ash and sand can balance the weight of the brick and prevent the brick from deforming due to uneven pressing.

4. Surface treatment

After pressing and spreading ash and sand, the brick will leave obvious marks. At this time, tools are needed for surface treatment. You can use a stone or prop with patterns to treat the surface of the brick to make it smoother and more textured.

5. Drying

The treated brick needs to be placed in a drying room for drying. The drying time is generally 3-4 days. During the drying process, pay attention to controlling the temperature and humidity. Excessive temperature and humidity will cause cracks on the surface of the brick or bubbles inside.

6. Packaging

The dried cement bricks need to be packaged. When packaging, it can be wrapped with plastic film or stacked with bamboo strips or wooden strips. The packaged cement bricks need to be placed in a dry, ventilated and light-proof place to ensure the quality of the cement bricks.

Summary

The above are the main process flow and precautions for making cement bricks. The production of high-quality cement bricks requires strict control of the quality and process of each link. Only by ensuring the high quality of raw materials and the standardization of operations can better quality and more practical cement bricks be produced.
