High flexural tensile strength concrete

Nowadays, fiber-reinforced concrete is often used to increase the flexural tensile strength of the material. This approach enables a reduction in the ratio of conventional reinforcement or its complete substitution, for instance in foundation slabs or industrial floors. Due to the fact that fibers contribute to flexural strength only to a minor extent, they are not used for producing structural components and, more specifically, elements subject to bending. In some cases, alternative reinforcement concepts based on plastic, glass or carbon fiber fabrics provide advantages compared to...
