Abstract:
Application of ferrocement in housing is presented here using local unskilled supervised labor and available materials in parts of India. The report is based on the large housing project partially supported by World Bank. In the design of Service Modules, two alternate schemes are proposed: one, using conventional brick walls and in-site or precast concrete roofing and the second, with a prefabricated service modules using ferrocement. Cost comparison between the two approaches is also given along with details of investigation using second alternative.

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.

The ferrocement applications described in this paper, developed by the Universidad Autonoma Metropolitana (UAM) and Instituto Politecnico National (IPN) of Mexico City, have been used with good results in different towns and slum areas, through a self-help construction program for low cost housing. Each of these applications presents an economical and practical solution for improving the physical living standards of people in developing countries.

One of the distinguishing features of ferrocement as compared to reinforced concrete is the larger number of finer cracks for the same stresses in the steel reinforcement. Designing ferrocement structures to satisfy recommended serviceability criteria in a manner similar to the design of reinforced concrete structures is a logical and rational approach to follow. Serviceability is greatly dependent on cracking and crack width under working load conditions. Thus the prediction of crack widths (average and/or maximum) is an important consideration in design. This paper is based on a number of recent investigations on the cracking of ferrocement elements: they include tests on flexural beams under static and fatigue loadings, tests on ferrocement prisms with and without transverse reinforcement subjected to direct tensile loads, and tests on internally pressurized model ferrocement cylindrical water tanks. The following aspects of cracking are clarified for both flexure and tension: cracking behavior; influencing parameters; observed variations of crack widths; crack width predictions and suggested design approach.

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.
