Concrete and reinforcement are the foundation of every modern building. Without properly executed concrete and adequately placed reinforcement, no object can have the necessary load-bearing capacity, durability, and safety. In Bosnia and Herzegovina, where climate conditions are demanding, the quality of concrete and proper installation play a crucial role in the longevity of the object.
In this detailed guide, you will learn everything about types of concrete, reinforcement, proper execution of works, as well as real prices in KM.
What is concrete and how it is made
Concrete is a building material that is made by mixing cement, water, aggregate (sand and gravel), and additives. After binding, concrete becomes solid and capable of carrying heavy loads.
The basic components of concrete:
- Cement
- Water
- Aggregate
- Additives
Concrete classes (MB marks)
In practice, different classes of concrete are used:
- MB20 – foundations and smaller load-bearing elements
- MB25 – slabs and beams
- MB30 – load-bearing elements
A larger mark means greater strength.
Concrete prices in BiH
- MB20: 150 – 180 KM/m³
- MB25: 170 – 200 KM/m³
- MB30: 190 – 230 KM/m³
Prices vary depending on the region and transportation.
What is reinforcement
Reinforcement is a steel component that is installed in concrete to increase its load-bearing capacity in tension.
- Rebar
- Reinforcement mesh
Reinforcement price
- 1.5 – 2.5 KM/kg
The total quantity depends on the project.
Concrete pouring process
Concrete pouring must be properly executed to achieve maximum strength.
- Preparing the substrate
- Installing formwork
- Installing reinforcement
- Pouring concrete
- Vibrating
Concrete maintenance
Concrete must be protected after installation.
- Maintaining moisture
- Protecting from sunlight
- Binding time: 28 days
Slab concreting
One of the most common works.
- Thickness: 10 – 20 cm
- Price: 80 – 150 KM/m²
Most common mistakes
- Poor water-to-cement ratio
- Insufficient vibration
- Poor reinforcement
Total costs (house 150 m²)
- Concrete: 8,000 – 15,000 KM
- Reinforcement: 6,000 – 12,000 KM
- Labor: 4,000 – 8,000 KM
Total: 18,000 – 35,000 KM
Tips for quality
- Use verified concrete
- Control the work
- Don’t save on reinforcement
Conclusion
Concrete pouring and reinforcement are key processes in construction. Quality work guarantees safety, durability, and a long life of the object.
