Pisos industriais de concreto reforçados com fibras de aço: estado da arte

Abstract

The steel fiber reinforcement concrete is a composite material. The concrete is the matrix and the reinforcement are fibers. In Brazil, it started to be used in the decade of 90, and nowadays it´s one of the most efficient solution for industrial floors, witch are very important structures because the whole production consists on it. A problem with these kind of floors is that it creates financial damages in the occurrence of interruption of industrial activities. Some fibers had been studied as an addition to the concrete, mostly the steel ones. The main types of concrete floors had been boarded, with emphasis on the reinforced with steel fiber, looking for it´s characteristics, interactions fiber x matrix, efficiency parameters, quality control, main pathologies and therapies, as well as existent loads and dimensions. It was concluded that the fiber steel performance has an important role in the control of propagation of the cracks, increasing the residual strength factors, even being able to increase the capacity of the structure, depending on the volume of fiber steel that is applied.
