Cellular fiber–reinforced concrete

Methods disperse reinforcement of concrete matrix using polypropylene, glass, basalt and metal fibers allows to make the construction of complex configuration, solve the problem of frost products. Dispersed reinforcement reduces the overall weight of the structures. The fiber replaces the secondary reinforcement, reducing the volume of use of structural steel reinforcement. Cellular Fiber concretes are characterized by high-performance properties, especially increased bending strength and tensile impact strength and fracture toughness. The reinforcement component is preferable to use mineral fibers or thin basalt fiber. Use of a polyamide fiber is allowed, but there are difficulties in forming the contact adhesion between the fiber and the matrix mineral aerated concrete. A feature of the mineral fibers is its high adhesion with the cement matrix
