Spalling may be a violent effect to fire-exposed concrete destroying the entire cross-sections or reducing the load-bearing capacity of a construction substantially. The network of large capillaries created by vaporized fibres allows for internal steam exhaust, thus preventing fire-spalling for several hours.
CHRYSO offers a full range of proven anti-fire spalling fibres and its expertise in adapted mix designs, especially for tunnel segments.
As a part of its complete range of tunneling solutions, CHRYSO dedicated macro-fibres allow for meeting the requirements of class
A, B and C shotcrete (EFNARC or ASTM standards). These fibres are designed for easy pumping, maximum rebound reduction and ultimate tensile strengths performances.
Combined with CHRYSO®Jet range of admixtures and our dedicated concrete mix-design know-how, they ensure a flawless and successful operation throughout the project.
