High-strength concrete

Field of application

• Manufacturing of pillars in high-rise buildings.
• Bridge decks with great slenderness.
• Pillars and beams of bridges.
• Concrete subjected to aggressive environments.
• Singular structures.

Advantages

• Great compressive strength, lower deformation, lower dead weight of the structure.
• Resistance to corrosion and abrasion, due to its lower porosity and higher density.
• More impermeable than standard concrete.
• Superior fire resistance. Avoids a structure having to be subjected to a specific fireproofing process.
• Allows formwork to be removed in a shorter period of time than usual.
• Same load-bearing capacity with less thickness. The required dimensions of the structure and weight are reduced, providing more usable space. For example, in bridges over rivers, where fewer pillars would be required, making execution more economical and faster, and the bridge would present less obstacle to water flow once constructed.
• It is used in building and civil engineering works.

Application system

It is applied in the same way as conventional concrete: by direct pouring, bucket, or pumping.

Formwork similar to conventional concrete.

Technical characteristics

* For strengths exceeding 80 MPa, a prior dosage study is required.
