From the point of view of both economy and strength, it is important that the fibres in fibre reinforced concrete should be utilized in an effective manner. This can be done by magnetic orientation of steel fibres. The fibres should be oriented in relation to the expected stresses, primarily in load bearing constructions in the tensile zone. A considerable improvement in the strength and deformation characteristics of the material is obtained in this way. The anisotropy which arises as a result is a feature of several building materials, and need not prove a disadvantage. Fibre concrete with oriented fibres can be used to advantage for planks, boards, non-loadbearing and loadbearing sheet materials, partitions, beams, studs, posts, handrails, pipes, and some composite constructions. Until such time as more reliable strength data have been documented, the material should be used only where the consequences of failure are not serious, for instance as floor covering and cladding for walls and ceilings. The material cannot be nailed but can be glued and drilled and affixed with bolts. The report also deals with corrosion protection of steel fibres situated on the surface, and the use of stainless fibres. /TRRL/
