![]() ![]() ![]() From the environmental point of view, GFRC are eco-friendlier materials than ordinary concretes since their application can decrease the emission of CO 2 by 17%. ![]() However, mechanical properties enhance as long as sufficient workability and uniform fiber distribution are assured. This results in cheaper structures both in manufacturing and maintaining even though GFRC are more expensive materials. Moreover, decreased thermal conductivity allows for better energy performance from the building’s point of view. All of this positively influences the mechanical behavior, durability, and corrosion resistance of concrete elements. Additionally, GFRC are characterized by enhanced tensile, flexural, and splitting strength impact, abrasion, spalling, fire, and freeze-thaw resistance as well as ductility, toughness, and permeability. First of all, because of their bridging abilities, they can limit the width, length, and total area of cracks. The comprehensive discussion on GFRC composition is presented together with the review of glass fibers’ influence on various concrete properties. The article highlights that glass fiber reinforced concretes (GFRC) can meet the requirements of Smart City better than ordinary concretes.
