International Forum on Appropriate Industrial Technology Held at New Delhi/Anand, India on November 20-30, 1978. Sisal Fibre Concrete for Roofing Sheets and Other Purposes

摘要

When building in rural areas in developing countries, roofing normally is the major difficulty. Concrete reinforced with sisal fibres is shown to have properties suitable for the production of thin sheets, e.g. for roofing. The production of sisal fibre concrete can be carried out manually by local craftsmen but can also be mechanized in different steps in order to increase the production rate and the quality. The fibre reinforcement gives the concrete higher tensile strength, higher deformation capacity and an improved crack distribution. If properly done, sisal fibre concrete has also all potentially good qualities of normal concrete, e.g. fire resistance, water tightness, durability, ease of production, low price. Sisal fibre concrete is also a low-energy consuming material. The products can be used in traditional as well as in more advanced building techniques.
