Concrete batching means the combination of concrete raw materials including cement, water, sand and gravel in such a way that it can be used to build concrete structures. Concrete batching process includes the following steps:
1. Preparation of raw materials: In this stage, cement, water, sand and gravel are prepared in certain quantities and with the desired quality.
2. Composition of materials: raw materials are combined in a certain ratio. This is usually done in a batching plant or at a concrete manufacturing site.
3. Mixing: The raw materials are combined and mixed using concrete mixers to produce a uniform material of high quality. At this stage, water is gradually added to the raw material to make the mixture soft and pumpable.
4. Transportation and storage: The produced concrete is transported to the construction site by concrete trucks. Concrete is stored in the compartments inside the truck so that it can be easily used at the construction site.
5. Pouring concrete: Concrete is poured in various forms, such as concrete forms or metal structures. After pouring, the concrete should be placed for at least a few days to dry and fully set.
Batching of concrete must be done carefully and in accordance with certain proportions so that high quality concrete can be used for the construction of concrete structures.
Are materials other than cement, water, sand and gravel used for batching concrete?
Yes, in some cases, materials other than cement, water, sand and gravel are also used to improve the characteristics of concrete and diversity in its design. Some of these materials include pozzolanic materials such as power plant ash, polymer fibers, metal fibers, polycarboxylates, lubricants, washing chemical agents, hardness intensifying agents, etc.
The use of these materials in concrete can improve mechanical properties, durability, resistance to corrosion and heat, strength and beauty of concrete. However, it should be noted that the use of any material should be done in compliance with safety and health standards and guidelines.
Can the use of other materials in batching concrete damage the quality of concrete?
The use of other materials in concrete batching may have advantages due to the diversity in concrete design and improving its properties, but if these materials are not added to concrete carefully and in compliance with safety and health standards and guidelines, it can damage the quality of concrete. hit
For example, the use of excessive amounts of washing chemicals can reduce the corrosion resistance of concrete, or the use of excessive amounts of water can reduce the strength of concrete. Also, the use of materials whose quality is unknown can reduce the quality of concrete.
Therefore, in order to use other materials in concrete batching, it is necessary to carefully research and ensure that these materials are compatible with concrete standards and are provided with appropriate quality. Also, the amount of use of each material should be used in the amount specified in the concrete formula.
