Reinforced Concrete Structures

Concrete is reinforced to give it additional strength - without such reinforcement, many building projects would not be possible. Steel fiber reinforced concrete can be used for various types of structures and components and can be made into almost any shape or size. The material is developed by incorporating steel reinforcement bars, plates or fibers into the traditional concrete mix.

Fibre steel was first used in the mid-1800s by French building contractor Francois Coignet. His own house, built with reinforced concrete, still stands some 150 years following construction. 

Typically used for retaining walls, highways, concrete foundations, and sewerage tanks,steel fiber reinforced concrete provides additional tensile strength for heavy duty construction projects. The steel reinforcement gives added strength by taking up the tension stresses, while the concrete takes up the compression stresses; meaning the two materials act together as resisting forces.

The coefficient of thermal expansion of concrete is similar to that of steel, eliminating internal stresses due to differences in thermal expansion or contraction. In concrete reinforcement, the cement paste hardens and adapts to the surface details of the steel, meaning that any stress can be effectively passed between the two materials. Steel bars are often roughened or corrugated to further enhance the bond between the concrete and steel. Adding alkaline producing carbonate Calcium causes a film passivatingto form on the surface of the steel, making it much more resistant to corrosion than it would be in neutral or acidic conditions.

Precision Drawell is concrete contractors who undertake many projects that make use of Fibre for Concrete. Some of the most typical structures include water treatment works and waste water treatment works as well as highway projects and flooding and coastal defense schemes. As steel fiber reinforced concrete contractors, Precision Drawell provides a full design and build apackage to suit any project.
