Engineering examination of the element and the connection
Several protection methods depending on the structure
Support from planning to execution control
Why is fire protection required for concrete elements?
Despite its durability, concrete can weaken when exposed to high heat. Evaporation of water trapped in the concrete can cause cracks and detachment of parts from the element, while at the same time the reinforcing steel inside it loses its strength.
Appropriate thermal protection helps slow down the heating of the element, reduce damage to the concrete and reinforcement, and maintain the load-bearing capacity for the duration specified in the design.
Reducing thermal damage to concrete
Slowing down the heating of the element and reducing the risk of cracking and layer detachment
Protection of the reinforcement steel
Reducing the rate of heating of the joint and maintaining its structural contribution
Maintaining carrying capacity
Helping the element withstand loads for the duration specified in the design
Adaptation to the existing or new structure
Choosing a solution that takes into account dimensions, the condition of the infrastructure, and finishing requirements
The process of planning and implementing the protection
1
Collecting element data
Examining plans, dimensions, reinforcement coverage and concrete condition
2
Setting the durability time
The requirement check applied to the elements and the structure
3
Choosing the protection system
Adapting a solution according to the infrastructure, exposure conditions and finish
4
Preparation of execution details
Defining surface preparation, system thickness, and junction details
5
Implementation and quality control
Control of infrastructure, materials, and continuity of protection
6
Inspection and documentation
Documenting the work and preparing the documents required for the project
Adapting the solution to the concrete elements
The system selection is made according to the type of element, the thickness of the cover on the reinforcement, the condition of the concrete, the required fire resistance time, the exposure conditions and the finishing requirements of the project
Control of execution and continuity of protection
The success of the protection depends on the condition of the foundation, the preparation of the concrete surface, the adjustment of the system thickness, and continuous application around the element. The support includes checking the details of the execution and providing solutions to complex points during the work
Possible methods for protecting concrete elements
Insulated cementitious system
Applying a thermal protection layer to the surface of the concrete element.
Dedicated coating system
Using a coating system selected according to the infrastructure and project requirements.
Wrapping with fire-resistant panels
Creating an insulated envelope around the element using dedicated panels.
Incorporating polypropylene fibers into concrete
A solution designed for a new concrete mix to reduce vapor pressure buildup upon exposure to heat.
