Concrete mixing and placement require close supervision to achieve good quality work. On site, materials such as cement, sand, and aggregate are measured correctly before mixing. Clean water is used to avoid contamination that could weaken the concrete.
The concrete is mixed until a uniform consistency is achieved. During placement, care is taken to avoid segregation. Concrete is poured steadily into formwork and compacted properly using rods or vibrators to remove air pockets.
Attention is given to weather conditions, as extreme heat can affect setting time. After placement, curing begins to help the concrete gain strength gradually. The surface is kept moist for several days.
Conclusion
In conclusion, proper concrete mixing and placement improve strength and durability. Good supervision ensures that structural elements perform as expected.
