INFLUENCE OF ELEVATED TEMPERATURES ON THE PERFORMANCE OF NANOMODIFIED FIBER-REINFORCED CONCRETES

Exposure to elevated temperatures has detrimental effects on the properties of concretes based on the Portland cement, leading to irreversible changes, up to total failure. One of solutions to improve resistance of structures after exposure to high temperatures may be the use of cement-based materials modified at the nanoscale.
