| Abstract | This paper deals with an analytical and experimental investigation of the mechanical properties of cement mortar reinforced with randomly oriented short steel wires. Analytically, the material is
treated as a composite and its properties are derived by the laws of mixture. The effect of random orientation of the short wires is taken into consideration by the introduction of dimensionless factors which
are derived on the assumption that the geometric centers of the wires are uniformly distributed in space and that any wire has equal probability of being oriented at any angle with the direction of the applied stress. Explicit expressions are given for moduli of elasticity and ultimate strength in tension and compression. In bending
and torsion, the composite is idealized as a bi-linear material to describe its behavior in the unwracked and cracked range provided that the volume fraction and length of fibers used exceed certain critical values which are suggested. Experiments were conducted and the results obtained are shown to be in good agreement with theoretically predicted values. |
