Frequent Failures of FRC Industrial Floors

Abstract:

Floors in industrial buildings are often loaded with heavy traffic or stored material. For this reason floors are often created by fiber-reinforced concrete. Fibers contribute to larger impact - or abrasion resistance. The issue of design of fiber concrete slabs is quite complicated. Poorly designed layer structure under slabs or poorly subsoil can have very important effect of result properties and create the first group of source of problem. The second group of causes of problems is real implementation of concrete slab primarily the amount of fibers and correct and even placement. If amount or placement of fibers are incorrectly then significant failure can arise. This paper deals with frequently failures of FRC floors in practice. It will be described several buildings in which were fiber concrete slab constructed and where some failure arose. It will be presented what kind and what range of failure arose. Causes of failures will be also described in this paper. Also possible solution of problem will be designed if it exist.
