7. Materials
Concrete
Concrete is a key material used in reinforced concrete structures.
Cement
Cement serves as the binding agent in concrete,
providing strength and durability.
Aggregate
Aggregates, such as sand and gravel,
provide volume and strength to concrete.
Water
Water is essential for hydration of cement, facilitating
the chemical reactions that lead to concrete hardening.
Batching, mixing and placing of concrete
spacer
6

8. Concrete Work
Batching
Precise measurement of concrete ingredients is crucial
for consistent quality.
Mixing
Thorough mixing ensures a homogeneous concrete
mix with uniform properties.
Placing
Concrete is carefully placed in the formwork,
ensuring proper compaction and density.
Compacting
Vibrating the concrete removes air pockets and
improves workability.
Curing
Curing involves maintaining moisture and temperature
to allow for proper hydration and hardening.
7

9. Reinforcement Work
1 Cutting and Bending
Reinforcement bars are cut and bent to
the required shapes and sizes.
2 Placement
Reinforcement bars are placed in the
formwork according to the design
drawings.
3 Stirrups
Stirrups are used to reinforce the shear
strength of concrete structures.
4 Lapping
Lapping involves overlapping
reinforcement bars to provide a
continuous reinforcing element.
8

10. Formwork
Temporary Mold
Formwork serves as a temporary mold for
concrete structures.
Requirements
Formwork must be strong, rigid, and capable of
resisting the pressure of fresh concrete.
9

11. Scaffolding
Temporary structure erected separately from
structural support scaffolds.
Provides easy circulation and working environment.
Required for all types of structures constructed above ground level.
Various stages of construction should be erected at convenient heights.
Only limited loads should be put on the scaffolding.
10

12. Equipment Used
Mobile Truck Mixer
Used to transport and mix concrete.
Concrete Pumper Truck
Delivers concrete from the
mixer to the desired location.
Vibrator
Used to remove air bubbles
and consolidate concrete.
