A Study of Affordable Roofing System Using Ferrocement And Bamboo Cement Panels

A Study of Affordable Roofing System Using Ferrocement And Bamboo Cement Panels Structural roofing system contributes substantially to the cost of construction of housing unit in normal situation. In the study undertaken, an attempt is made to reduce the cost of construction by developing an Affordable Roofing System (ARS) consisting of a grid containing primary beams and secondary beams of triangular shape supporting Ferrocement precast infill panels and Bamboo-cement precast infill panels. Precast rectangular infill panels have a shorter dimension of 0.5 m with an aspect ratio of 1.0, 1.5 and 2.1.Panels are designed using cement mortar of compressive strength 7. 5 N/mm2, wiremesh of yield strength 250 N/mm2 and bamboo of yield strength 179 N/mm2.Construction and Demolition waste is used as partial replacement for sand. Expanded Polypropylene Fibres are used for arresting cracks and improving ductility. Primary as well as secondary beams are designed using M20 grade concrete and Fe415 steel. Reliability analysis for the proposed Affordable Roofing System (ARS) and conventional Reinforced Cement Concrete (RCC) roof is performed and compared. The level of structural safety is found to be same for the both roofing systems. Cost analysis is done for the proposed ARS and compared with conventional RCC roof slab. It is found that the proposed Affordable Roofing System is 36.78% economical than conventional reinforced cement concrete roofing system. Further, it is also found that Affordable Roofing System (ARS) made of Bamboo-cement precast infill panels are comparatively more economical than that of Ferrocement precast infill panels. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of The Institution of Engineers (India): Series A Springer Journals

Abstract

Structural roofing system contributes substantially to the cost of construction of housing unit in normal situation. In the study undertaken, an attempt is made to reduce the cost of construction by developing an Affordable Roofing System (ARS) consisting of a grid containing primary beams and secondary beams of triangular shape supporting Ferrocement precast infill panels and Bamboo-cement precast infill panels. Precast rectangular infill panels have a shorter dimension of 0.5 m with an aspect ratio of 1.0, 1.5 and 2.1.Panels are designed using cement mortar of compressive strength 7. 5 N/mm2, wiremesh of yield strength 250 N/mm2 and bamboo of yield strength 179 N/mm2.Construction and Demolition waste is used as partial replacement for sand. Expanded Polypropylene Fibres are used for arresting cracks and improving ductility. Primary as well as secondary beams are designed using M20 grade concrete and Fe415 steel. Reliability analysis for the proposed Affordable Roofing System (ARS) and conventional Reinforced Cement Concrete (RCC) roof is performed and compared. The level of structural safety is found to be same for the both roofing systems. Cost analysis is done for the proposed ARS and compared with conventional RCC roof slab. It is found that the proposed Affordable Roofing System is 36.78% economical than conventional reinforced cement concrete roofing system. Further, it is also found that Affordable Roofing System (ARS) made of Bamboo-cement precast infill panels are comparatively more economical than that of Ferrocement precast infill panels.
