Strength of Corrugation in Roofing Sheet with Various Fibres

Abstract

Due to tearing out at its corrugations because of high wind and impact loads most of the corrugated roofing sheets have damaged. By using fibre reinforcement the strength of these sheets can be improved. The fibres play the role of crack arrest and absorb energy. In this research paper the fibre namely polyester, glass fibre, coconut coir fibre and fly ash are used as reinforcement in cement matrices for producing corrugated roofing sheets and it has been investigated and reported. These roofing sheets were cast by hand and the strength of the corrugations of the sheets in terms of splitting due to water absorption test, impact load and flexure test were experimentally evaluated. It is identified that the strength of the fibre sheets due to buckle strength and impact loads increased as compared to the corrugated sheets without fibres. This study has shown that asbestos can be replaced by these fibres, in the fabrication of corrugated roofing sheets.
