Formwork preparation: The formwork, which is a structure that will contain the concrete while it is poured and cured, must be built. The formwork should be strong, waterproof, and leak-proof.
Reinforcement placement: The steel reinforcement bars must be placed inside the formwork to give the concrete greater tensile strength. The bars should be secured with wire or reinforcement connectors to prevent them from moving during the pouring process.
Concrete pouring: The concrete is poured into the formwork and compacted with a vibrator to eliminate air pockets and ensure good adhesion to the reinforcement. It is important to check the level of the mix to ensure that the column is straight and uniform.
Formwork removal: After the concrete has cured, the formwork can be removed. It is important to do this carefully to avoid damaging the column.
Curing: To ensure optimal strength, the column must be properly cured. This involves keeping the concrete moist for several days or even weeks, and protecting it from direct sunlight and extreme temperatures.
In summary, to cast a concrete column, it is necessary to prepare the formwork, place the reinforcement, pour and compact the concrete, remove the formwork, and finally, properly cure the column to ensure its strength and durability.
