STUDY ON IMPROVEMENT IN STRENGTH PROPERTIES OF CORRUGATED ROOFING SHEETS WITH THE ADDITION OF VARIOUS FIBRES IN THE MORTAR

Emphasis on the development of new materials and technology has been there for the past few decades, especially in developing countries like India, so that the overall cost of construction becomes affordable by the people. Further, countries like India have a social obligation of providing shelter to all, which they strive very hard to fulfil within a reasonable time. If overall economy in the construction of shelter especially to economically weaker sections of society is to be achieved, then, economy in each major component of shelter, to the extent possible has to be realized. Roof, is one of the main building element, consumes about 20% of the total cost of construction. Asbestos cement based roofing and other light roofing materials are very commonly used in the construction of houses and industrial buildings, not only in India, but in all other developing countries of the World. In spite of the fact that asbestos-based roofing elements and products pose health hazards, ban on their use has not been effectively enforced. However, there exist alternate fibres instead of asbestos, which have the potential to use in roofing materials. Most of the corrugated roofing sheets have damaged due to tearing out at its corrugations by high wind loads and impact loads. Continuous dredging of sand from the earth or river bed causes adverse impact on environment and water source. So Usage of manufactured sand may prevent environmental disaster like ground water depletion, water scarcity, threat to the safety of bridges, dams etc. Hence in this project an alternative material to sand namely M-sand is fully replaced for aggregate.
