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.

The influence of grading and maximum size of natural quartz sands on the workability of mortars was studied. Both the grading and fineness modulus were found to affect the water requirement. Graphs are presented for the effect of grading, specific surface of sand and cement content on water requirement in mortars made with sands of maximum size 2.4 and 1.2 mm, respectively, and grading zones are proposed for these sands. Optimal sand composition was also found for fine sand with maximum size 0.6 mm.

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.

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.
