  • High-rise structures or structures subject to significant stress.
  • In all structures where it is required to obtain high resistance at 28 days or there is an interest in reducing the sections.
  • In wide-span bridge superstructures and where it is required to improve the durability of the elements.
  • Where low water/cement ratios are needed (storage tanks, dock structures, structures in contact with sewage, etc.)

  • The resistance obtained offers the possibility of smaller sections and therefore a lower weight of the structure.
  • Its dense and slightly porous matrix makes it low permeability to gases and liquids.
  • They protect the reinforcing steel, increasing the durability of the structure.
  • It has high fluidity that makes it possible to place it even in areas with a high density of reinforcing steel, allowing greater performance in the execution of works.
  • Greater resistance to hydraulic abrasion and impact.
