1. Preparation steps before pouring concrete

Before carrying out any type of work, preparation is always a prerequisite to help the process go more smoothly. The more effort and time spent from preparation, design until construction, the higher the likelihood of construction success. So before pouring concrete, what are the items you need to prepare: 

• Consider carefully the time, amount of manpower needed, machinery items, etc. that are reasonable for the concrete pouring process.
• Inspect in advance the size, shape, and whether there are any errors in the concrete mold.
• The amount of raw materials needed for construction such as cement, sand, stone, iron and steel belts, etc. ensures the quality of input requirements.
• Carefully check the scaffolding, working floor, reinforced steel or prepare wooden planks in advance to make the floor convenient for the construction worker.
• Provide a plan to prevent problems with concrete compactors. If any damage is detected, it should be fixed immediately before pouring concrete.
• Clean the reinforcement and formwork to begin construction. Remember to always ensure necessary hygiene and safety during construction.

2. Standard column concrete pouring process

Step 1: Take the trough and pour ready-made concrete into the mold.

Step 2: Note that the standard height for pouring concrete is estimated to be no more than 2.

Step 3: Along the vertical line to bring the dress inside. Builders can use compactors with a required depth of each concrete layer of about 30 - 50cm. The compaction process takes 20 - 40 seconds and carefully monitors the situation to avoid dislocating the reinforcement position.

Step 4: For house structures with doors, when pouring concrete on columns, it is necessary to seal the door first. Then, continue pouring the concrete above. 

Step 5: There is pitting in the layer below the column when concreting the column. Due to the accumulation of aggregates at the bottom of the column. To handle this case, the construction worker must add 10 - 20cm of thick cement mortar before pouring concrete on the column.

3. Technical notes when pouring concrete columns

When pouring concrete columns of any construction project. Regardless of the level and scale, large or small, workers always need to comply with technical specifications and notes. Helps the pouring process go as smoothly as possible:

- Before pouring concrete

Clean the concrete in the middle of the reinforcement with clean water several times. Continue watering the diluted cement to bond the old and new concrete together. Consider carefully when there is a request to insert additional formwork between the column gap and the wall of the house. On columns close to the wall of the next house because there is a high possibility that it will be difficult to remove later. You can adjust it by adding foam panels instead of formwork panels. And complete the first step in the pouring process.

- While pouring concrete

• Avoid maintaining a distance of more than 1.5 - 2m when measuring the free fall height of concrete, avoiding causing segregation of concrete.
• Carefully consider the appropriate type of compactor for different concrete structure characteristics. Such as table compaction for floors or punch compaction for columns and beams, table compaction for floors.
• Note that the column concreting process should always continue to ensure project construction progress. And avoid errors that occur while pouring concrete columns. Apply the principle of continuous pouring for concrete with a height of  <5m and walls usually with a height of <3m.
• In particular, you should not pour concrete columns in bad weather.

- After completing the concrete pouring

At this time, the column concreting process is almost completed. The worker's task now is to adjust the position of the reinforcement accordingly (column center position). To avoid causing heart misalignment, wasting time and affecting the quality of the later editing phase.
