Self Healing agent, Basilisk, for concrete basin

Water basin repairs itself due to Self-healing Concrete

A water basin of Port of Rotterdam has been constructed with special concrete walls. Due to addition of Basilisk Healing Agent to the concrete the walls will be able to heal itself when cracking occurs. The system is based on bacteria which, when subjected to water contact, will precipitate limestone which will gradually seals the cracks. The technology has been developed at the TU Delft and has been applied in practice due to the corporation of BAM Infra and Basilisk. Available on exclusive base in Belgium through Fortius, Diest

The basin is tank constructed out of four concrete walls. The basin has a length of 47 meters, a width of 5.5 meters and a height of 5 meters. Two walls has been constructed with plain concrete, whereas the other walls has been constructed with the addition of Basilisk Healing Agent.

During the construction there has been no noticeable difference observed in the workability of the Self-healing concrete mixture compared to the plain mixture. Also tests show that there has been no significant difference in the strength development comparing both mixtures (mixtures where identical except the addition of the Self-healing additive).

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.
