Raw Materials
The raw materials for cement bricks typically include cement, aggregates, water, and sometimes additives. Cement, usually Portland cement, serves as the binding agent, providing the necessary strength and hardness through the hydration process. Aggregates, which account for a significant proportion of the brick composition, consist of materials like sand, gravel, crushed stone, or recycled aggregates. They enhance the structural integrity, reduce shrinkage, and affect the texture and density of the bricks. Water is essential for initiating the chemical reaction of cement hydration, enabling the mixture to set and harden. Additionally, additives such as fly ash, slag, or plasticizers may be incorporated. Fly ash and slag can improve the workability of the mixture, enhance durability, and reduce production costs. Plasticizers help increase the plasticity of the mix, making it easier to mold into the desired shape while ensuring the quality of the final product.
Production Rate
The production process of cement bricks generally includes the following steps:
- Raw material preparation: Gather the necessary raw materials, mainly cement, aggregates (such as sand, gravel, or crushed stone), water, and sometimes additives like fly ash or plasticizers. Weigh and measure these materials accurately according to the specific mix design to ensure the desired quality of the cement bricks.
- Mixing: Put the weighed raw materials into a mixer. The mixer rotates to blend the materials evenly. During this process, water is added gradually to form a homogeneous mixture. The mixing time and speed are carefully controlled to achieve the right consistency and workability of the mixture.
- Molding: The mixed material is then placed into brick molds. The molds are usually made of steel or plastic and are designed in the shape and size of the desired cement bricks. The mixture is pressed or vibrated in the molds to remove air bubbles and ensure a dense and uniform structure. This can be done by using mechanical presses or vibrating tables.
- Curing: After molding, the cement bricks are removed from the molds and placed in a curing environment. Curing is a crucial step to allow the cement to hydrate and gain strength. The bricks are typically kept in a humid and warm environment, either in a curing chamber or covered with plastic sheets or sprayed with water regularly. The curing time usually ranges from several days to a few weeks, depending on the type of cement and the environmental conditions.
- Inspection and quality control: Once the curing process is complete, the cement bricks are inspected for quality. This includes checking their dimensions, shape, surface finish, and strength. Samples of the bricks may be tested in a laboratory to ensure they meet the required standards and specifications. Bricks that do not meet the quality criteria are rejected or recycled.
- Packaging and storage: The qualified cement bricks are then packaged, usually by stacking them on pallets and wrapping them with plastic or other packaging materials for easy transportation and storage. They are stored in a dry and well - ventilated area to prevent moisture damage and ensure their quality is maintained until they are ready to be shipped to the construction site or other destinations.
Here are some examples of the formula ratios for fly - ash bricks:
Example 1
- Fly ash: 60% - 70%
- Lime: 15% - 20%
- Gypsum: 3% - 5%
- Aggregates (such as coal cinder, stone chips, etc.): 10% - 20%
Example 2
- Fly ash: 55% - 65%
- Cement: 10% - 15%
- Lime: 10% - 15%
- Gypsum: 3% - 5%
- Sand: 10% - 20%
The proportion of cement, stone and sand varies depending on the different strength grades of concrete and the application scenarios. Here are some examples of common proportioning ratios:
C15 concrete
- Cement : Sand : Stone = 1 : 2.47 : 4.76
- Quantity per cubic meter: 305 kg of cement, 750 kg of sand, 1450 kg of stone, and 180 kg of water.
C20 concrete
- Cement : Sand : Stone = 1 : 2.1 : 3.82
- Quantity per cubic meter: 343 kg of cement, 730 kg of sand, 1300 kg of stone, and 170 kg of water.
C25 concrete
- Cement : Sand : Stone = 1 : 1.76 : 3.33
- Quantity per cubic meter: 398 kg of cement, 696 kg of sand, 1302 kg of stone, and 175 kg of water.
C30 concrete
- Cement : Sand : Stone = 1 : 1.48 : 2.78
- Quantity per cubic meter: 461 kg of cement, 682 kg of sand, 1270 kg of stone, and 175 kg of water.
These ratios are for reference only. In actual proportioning, adjustments need to be made according to the characteristics of raw materials (such as the strength grade of cement, the silt content of sand, the particle size of stones, etc.) and specific engineering requirements. At the same time, the use of additives such as water-reducing agents and retarders should also be considered to improve the performance of concrete.
Cement bricks have several requirements for aggregates, which mainly include the following aspects:
- Particle size distribution: The particle size of the aggregate should be properly distributed. Generally, a combination of coarse and fine aggregates is used. Coarse aggregates usually have a particle size of 5 - 20 mm, and fine aggregates have a particle size of less than 5 mm. This ensures the compactness and workability of the cement brick. If the particle size is too large, it may be difficult to form the brick, and if it is too small, the porosity of the brick may increase, affecting its strength.
- Shape and surface texture: The shape of the aggregate particles is preferably close to spherical or cubic, which is beneficial to the filling and compaction of the particles in the brick, reducing the void ratio. Aggregates with a smooth surface texture can reduce the amount of cement paste required to coat the particles, which is beneficial to improving the workability of the mixture and reducing costs. However, if the surface is too smooth, the bonding force with the cement paste may be insufficient. Therefore, aggregates with a certain roughness are often preferred to enhance the bonding strength with the cement matrix.
- Strength and hardness: The aggregate should have sufficient strength and hardness to withstand the pressure and external forces during the production and use of cement bricks. Otherwise, the aggregate may be crushed, which will affect the overall strength and durability of the cement brick. Usually, aggregates such as granite, basalt, and limestone, which have high strength and hardness, are commonly used.
- Cleanliness: The aggregate should be clean and free from impurities such as clay, silt, organic matter, and harmful substances. Impurities will reduce the bonding strength between the aggregate and the cement paste, and may also affect the setting and hardening of the cement, thereby reducing the quality of the cement brick. Therefore, the aggregate needs to be washed and screened before use to ensure its cleanliness.
- Water absorption: The water absorption of the aggregate should be appropriate. If the water absorption is too high, it will absorb a large amount of water from the cement paste, resulting in a decrease in the workability of the mixture and affecting the strength and durability of the brick. On the other hand, if the water absorption is too low, the bonding effect with the cement paste may be poor. Generally, the water absorption of the aggregate is required to be within a certain range, usually less than 3% - 5%.
- Chemical stability: The aggregate should have good chemical stability and should not react chemically with the cement or other components in the mixture, which may cause adverse effects such as volume expansion, cracking, and reduced durability of the cement brick. For example, aggregates containing active silica should be avoided when using high - alkali cement to prevent alkali - silica reaction.
