Concreto reforçado com fibras: tipos, mecanismo de ponteamento de fissuras, projeto da mistura, desempenho e guia de construção
Concrete carries compression very well, but it has limited tensile capacity. Shrinkage, temperature change, bending, impact, or restraint can create tensile stress. Once that stress exceeds the capacity of the cement matrix, a crack begins. Fiber reinforced concrete uses short, discrete fibers to control how those cracks form and grow. The fibers spread through the mix. […]
