TENSILE STRENGTH OF REINFORCED MICROCONCRETE
The object of this research is to determine the crack controlling ability of wire fabric and fibres in concrete slabs. The experimental results of uniaxial tension and bending tests on slabs of microconcrete are presented. The influence of type and amount of reinforcement on crack propagation and structural strength is evaluated from the results of twenty eight uniaxial tensile tests and sixty bending tests on thin sections (18 - 38 mm thick). A theoretical analysis of ultimate moment capacity indicated that fine wire reinforcement imparts a reserve of strength not accounted for in the conventional theory of reinforced concrete. Based on homogeneous properties ascribed to reinforced microconcrete, and limiting deflection criteria, working stresses for design purposes are suggested.
