RAAC in the UK: a structural strengthening approach using aluminium telescopic beams

For many years, Reinforced Autoclaved Aerated Concrete (RAAC) has represented a significant structural challenge within the UK’s public building estate. Schools, hospitals and other essential facilities have been forced to close, restrict use or rely on extensive temporary propping due to concerns over sudden structural failure.

EPX50LT: Extending Seasonal Use of Epoxy Polymer Overlays

Epoxy polymer overlay systems are designed to protect concrete structures and prolong the life of bridge decks and elevated concrete decks. Much of the wear and damage to these structures can be traced to corrosive de-icing chemicals that can migrate into the concrete and through cracks in the structure. Over time, if left unprotected, the […] <p>The post EPX50LT: Extending Seasonal Use of Epoxy Polymer Overlays first appeared on CCR-Mag.com.</p>
