Reinforced performance
WebTools. High-performance fiber-reinforced cementitious composites (HPFRCCs) are a group of fiber-reinforced cement-based composites which possess the unique ability to flex and self-strengthen before fracturing. This particular class of concrete was developed with the goal of solving the structural problems inherent with today’s typical ... WebSuffice it to say, reinforced concrete is a French invention from the middle of the 17th century, but it may owe something to the British invention of chicken wire in 1844. Joseph-Loius Lambot made a ferro-cement boat and took out a patent for the idea in 1855 ( Courland, 2011, p. 218).
