Abstract:
Variations in the form and use of conventional ferrocement made with plain mortar are limited by the requirement for fine meshes to control concrete cracking. If fibrous mortar is used, the steel wire fibers assist in distributing cracks and use can be made of much heavier meshes woven or loomed from high tensile wire. The outcome is a high strength material for which flexural properties can be designed and predicted with some accuracy, and which offers improved energy absorption and impact loading properties.

Although some practical specifications are available for the construction of ferrocement boats, to the best of the author's knowledge no technical specifications for the construction of ferro-cement structures have yet been published. Specifications are essential if the use of ferrocement is to become widely accepted and if the gap between the "try and see what happens" approach and advanced research results is to be reduced. Based on 1) tests at the University of Illinois at Chicago Circle of model pressurized ferrocement water tanks where cracking and leakage characteristics were studied, 2) the experience in ferrocement and knowledge of its mechanical behavior and 3) an extensive survey of ferrocement related literature where some forms of specifications or recommendations were found and analyzed, the author has developed tentative recommendations for the construction of ferrocement water tanks. Although these recommendations are written specifically for water tanks, they may be used either as a model for other types of ferro-cement structures or as part of a more general and complete specification document on ferrocement.

A theoretical model is presented to predict the width and spacing of cracks in ferrocement elements in tension. A parametric study was also conducted to study the influence of parameters such as bond stress, volume of reinforcement, size of reinforcement, properties of mortar and reinforcement on the width and spacing of cracks. The theoretical results indicate that the spacing and width of cracks are significantly affected by bond stress, diameter and volume of reinforcement. An experimental investigation was conducted on ferrocement specimens in tension with varying steel content and the results obtained are shown to be in agreement with theoretically predicted values. Practical guidelines are suggested for the control of tensile cracks in ferrocement elements.

A review of the basic characteristics of ferrocement, as it is distinguished from conventionally reinforced concrete or fiber reinforced concrete, is made. Problems of definition and performance are discussed in light of needed design criteria and future research needs are outlined.
