The ferrocement is a composite building material similar with the reinforced concrete, formed by a matrix of concrete reinforced with small diameter continuous wire mesh. It can be used for erection of reinforced concrete floors as well as for rehabilitation of this type of floors or wooden ones. The use of ferrocement for the floors erection is an efficiently solution in many situations. As well, the utilization of ferrocement for the rehabilitation of building elements is a possible solution and, in some cases, it appears as the only alternative to the solutions of rehabilitation currently applied (ex. for elements to which severe restriction in what concerns the cracking are imposed or for those elements having an architectural distinguished form). The advantages of using ferrocement instead reinforced concrete result from ferrocement particularities: small thickness of the element (10… 50mm), uniformly spread of reinforcement, the reduced cracking process, a better ductility and a high resistance to impact.
