Technology background
Loads of special works structurally deficient or obsolete. engineers, local and national government seeking new ways to build better structures, reduce travel time and improve repair techniques. One of the biggest challenges is the long-term durability in the works, creating of deterioration and maintenance problems.
Technology description
Concrete mix with fibers, including industrial waste from the steel manufacturing, with mechanical properties superior to commonly known. The resulting material offers superior technical characteristics, including ductility, strength and durability, can provide highly moldable beams with a high quality surface appearance and a new approach to the reconstruction of superstructures.
Problem Fixed
Its properties make it durable and can be used in abrasive environments or subjected to severe impacts, as in the airport industry, oil and nuclear. It can also be used in the rehabilitation or strengthening mass of existing structures, its thixotropy allows for easy application of the product. viaducts or bridges recovery projects of road and rail systems can employ reinforcements using this resistant material, reducing the risk of these works to collapse.
Advantages
- Ideal for use as reinforcement material.
- Easy to install in environments with space constraints.
- Fast hardening and strength gain of the cured few days.
- Long-term durability.
- Resistance five times greater compared to conventional concrete.
- carrying capacity loads after fissured.
- Ability to withstand tensile stresses, allowing lower amounts of steel.
- Construction of smaller structural elements to support the same loads as compared to conventional concrete.
- High energy absorption capacity.
- architectural versatility, It can be used in panels or facade elements slender.
Applications
- precast industry or as reinforcement material in existing structures, whose operation can not be stopped, such as, in bridges or viaducts.
- Structural maintenance works.
- Material for the military industry, security and defense.
- Applications where there are high energy release rates.
- Construction or repair of bridges.
- Reinforcement and protection in existing buildings or to design new structural members.
