Vault/wall consolidation of Sint Donatus Tower

The Sint Donatus tower in the citypark of Leuven, was part of medieval city walls and was built in 1150. This tower will be transformed into a touristic attraction in the park.

Triconsult, a specialised engineering consultant was called in to advise on the stability and restoration of the tower. Aslan 100 rebars were specified to consolidate the stone blocks of the walls/vault of the tower and to anchor the walls together. Horizontally ,the Aslan 100 GFRP rebars were positioned into the joints and also drilled in vertically. They were used in combination with AFRP-masonry mesh to create a ringbeam to take the horizontal forces of the vault.

Contractor DENYS NV of Gent rebuilt the vault and the walls.

Fortius steelfibers with ATG-certificate until 2020

Recent werd de technische goedkeuring met ATG certificatie verleend door het Butgb aan de staalvezels MPZ & MPZ HT die in België gecommercialiseerd worden door FORTIUS.

Deze ATG certificatie is geldig tot 2020.

Bert Kriekemans, algemeen directeur van FORTIUS legt uit: “ als leverancier van composieten voor het versterken van bestaande en nieuwe structuren wordt Fortius geconfronteerd met de problematiek van het efficiënt wapenen van stortklare beton. FORTIUS heeft reeds een reputatie opgebouwd als leverancier van non ferro materialen om beton te versterken. Om het gamma compleet te maken, bieden wij nu ook staalvezels aan. Deze ATG certificatie is een kwaliteitsborging”

Beton versterkt met staalvezels biedt mogelijkheden om traditionele wapening weg te laten. Dit betekent een sterke reductie van de arbeid op de werf. Door gebruik van staalvezelbeton wordt de wapening en beton in één arbeidsgang geplaatst.

GFRP rebars for renewal of roof – domes of Cathedral in Tenerife

The restoration project of San Cristobal de La Laguna Cathedral, in the island of Tenerife used Aslan 100 in the ribs, beams and columns of the roof . This Cathedral was built in the early 1900 and one of the first Spanish projects to use concrete as structural material and the adverse climate conditions in the zone caused, along the years, a considerable damage in the whole roof.

After being closed to the public for 12 years, in 2011 it was finally decided to undertake the complete substitution of all the domes and vaults of the temple, with the determination to use an innovative mix of fiber-reinforced concrete and GFRP rebars for the project in its entirety, avoiding further corrosion problems.

Architect José Miguel Márquez and CESMA Engineers were commissioned to develop the replacement project, which had to respect the initial state and spirit of The Cathedral while fitting in a tight budget.

The 22 domes , beams and pillars are all reinforced with the Aslan 100, GFRP rebars of Fortius.
