Infographic “Rebar placement and concrete pouring for monolithic floor slabs”
Rebar placement and concrete pouring are the most critical stages in the construction of monolithic floor slabs, directly affecting the strength and durability of the structure. The correct sequence of these operations ensures the required rigidity and stability of the slab and prevents deformation in the future. This infographic will help you visually understand the key steps required for successful rebar placement and concrete pouring.
Rebar placement
Place reinforcement bars (metal rods that reinforce concrete) on the formwork, leaving a gap from the edges for uniform concrete coverage. This is necessary so that the concrete properly envelops the reinforcement, providing reliable protection and preventing corrosion.
Frame inspection
Tie the reinforcement bars together with wire (thin metal wire used to connect reinforcement) to create a strong reinforcement cage. The cage must be rigid and level to ensure even load distribution across the entire structure. In Italy, according to UNI EN 13670 standards, the quality of the reinforcement cage must be checked before concrete pouring.
Concrete pouring
Pour the concrete in even layers, compacting the mix with a vibrator (a special tool used to remove air bubbles from concrete) to prevent the formation of air voids (empty spaces that can reduce concrete strength). This is essential for achieving the required strength and durability of the floor slab.
Concrete curing
Cover the slab surface with plastic film and moisten it for several days to prevent cracking of the concrete. Proper curing is required for correct concrete hardening and to prevent rapid moisture evaporation, which can lead to strength loss. According to Italian construction standards, such curing measures are mandatory to ensure the durability and reliability of the structure.
Instructions for using the guide “Rebar placement and concrete pouring for monolithic floor slabs”
- Rebar placement: Place reinforcement bars on the formwork, leaving a gap from the edges for uniform concrete coverage.
- Frame inspection: Tie the reinforcement bars together with wire to form a strong and level reinforcement cage.
- Concrete pouring: Pour concrete in even layers, compacting the mix with a vibrator to prevent air voids.
- Concrete curing: Cover the surface with plastic film and keep it moist for several days to prevent cracking.
By following these instructions, you will be able to properly carry out rebar placement and concrete pouring, ensuring the strength and long-term durability of your monolithic floor slab.
