Abstract

Fixed spherical dome biogas reactors are popular in Nepal for the production of biogas from waste materials. Current practice uses heaped soil as temporary formwork for an unreinforced concrete dome. This paper explores the structural requirements of biogas domes and presents a potential alternative construction process using air-supported flexible formwork that would be suitable for use in Nepal. A prototype dome was created to assess the feasibility of the formwork system. Load testing of the dome was undertaken to confirm structural performance. The results show that an air supported formwork system would be feasible for use in biogas domes with the formwork fabricated easily on site with only basic materials and fixings.
