The production process of steel fiber castables can be simply divided into the following steps:
1. Material preparation: First, the basic materials of concrete need to be prepared, including water, cement, fine aggregate and coarse aggregate. In addition, steel fibers are required as reinforcement. The steel fibers can be ordinary steel wires, steel wires cut into segments or specially shaped steel fibers.
2. Mixing: Add cement, aggregate and steel fiber into the mixer for thorough mixing. Make sure that the steel fibers are evenly dispersed in the concrete and fully combined with the cement and aggregate.
3. Adding admixtures (optional): According to needs, other chemical admixtures can be added during the mixing process, such as plasticizers, water reducing agents, waterproofing agents, etc. These admixtures can improve the fluidity, durability and workability of concrete.
4. Stirring: Stir the material to a uniform state through a mixer or a concrete mixer truck. Make sure that the steel fibers in the concrete are well dispersed and fully combined with other materials.
5. Pouring: Pour the mixed steel fiber castable into the predetermined position, such as floor, wall, beam and column, etc. Using proper tools and techniques, ensure that the concrete covers the target area evenly and removes air pockets.
6. Anti-crack treatment (optional): According to needs, after pouring, the surface can be treated with anti-crack, such as spraying anti-crack agent or covering reinforced mesh. This helps control crack propagation in the concrete, improving its overall toughness and durability.
7. Curing: After the pouring is completed, the steel fiber castables need to be cured to ensure that the strength and performance of the concrete are at their best. Wet curing usually involves spraying water, covering with a damp cloth, or using a misting system.
The above are the production process steps of general steel fiber castables. The specific parameters and step sequence in the process may be adjusted according to different product requirements and production equipment. During the production process, relevant quality control standards and safety operating procedures should be strictly followed to ensure that the quality and performance of the steel fiber castable meet the requirements.
