Mechanical, Durability and Thermal Properties of Foamed Concrete Reinforced with Synthetic Twisted Bundle Macro-Fibers

The use of foamed concrete (FC) in the construction sector has been rapidly growing over the past few years as a result of the several advantages it possesses in comparison to traditional high-strength concrete. FC, on the other hand, suffers from a number of deficiencies, such as brittleness, limit...
