Concrete is a mixture of cementitious materials, aggregates and water, mixed in appropriate proportions. It is an artificial stone that hardens after a certain period of time. It is the core material of today's construction projects and is widely used. So what are the important links in concrete production?
1. Raw material procurement and quality control: The quality of concrete is affected by raw materials, including cement, aggregates, admixtures and water. In the process of concrete production, it is necessary to select high-quality raw material suppliers and conduct strict raw material quality control to ensure that the raw materials meet the design requirements and standards.
2. Mix ratio design: The mix ratio is the proportional relationship between various raw materials in concrete, which plays a decisive role in the performance and strength of concrete. Reasonable mix ratio design can meet engineering requirements and improve the strength and durability of concrete.
3. Concrete mixing and mixing time control: In the process of concrete production, raw materials such as cement, aggregates, admixtures and water need to be mixed to form a uniform concrete slurry. The control of mixing time is crucial to the performance and uniformity of concrete.
4. Pouring and vibrating: Pour the mixed concrete into the mold or construction site for pouring, and then vibrate the concrete using vibrating equipment. The pouring and vibrating process can ensure the fluidity, density and uniformity of concrete, and improve the strength and durability of concrete.
5. Maintenance: After the concrete is poured, it needs to be maintained to control the evaporation of water and maintain the humidity of the concrete. The curing time and curing conditions have an important impact on the strength development and durability of concrete.
6. Quality inspection: The quality inspection of the produced concrete, including strength test, impermeability test, shrinkage test, etc. Quality inspection can ensure that the concrete meets the design requirements and standards.
7. Waste treatment: Waste concrete, wastewater and waste materials will be generated during the concrete production process. The treatment and recycling of these wastes can reduce environmental pollution and resource waste.
8. Safety management: During the concrete production process, it is necessary to strictly abide by the safety operating procedures to ensure the safety of production personnel, and take necessary protective measures to reduce the risk of accidents.
