Abstract:
The presence of wire mesh reinforcement in ferrocement improves crack resistance, impact strength, and toughness. Evenly distributing layers of wire mesh across the cross section of ferrocement is a tedious and labor-intensive operation. In practice, it might be easier if the layers of wire mesh were bundled. The bundled reinforcement can be placed near the top and bottom surfaces or at the midsection of the element. The effects of the reinforcement arrangements on strength and deformational characteristics of ferrocement in direct tension and simple bending were studied experimentally and the results are discussed in the paper. The conclusion is that a reinforcement arrangement in which the wire mesh is bundled and placed near the surfaces is preferred, from the point of view of first crack strength and crack characteristics.
