  • An assessment of water absorption of a lightweight polyester resin reinforced sawdust bio-composite 
    Dilrukshi, R.M.N.; Panamgama, L.A. (Faculty of Science, University of Ruhuna, Matara, Sri Lanka, 2022-01-19)
    The main objective of this study was to introduce a waste material (an equal portion mixture of Mahogany/Ginisapu sawdust) as a reinforcement filler in making polyester composites. In this study different contents of raw ...
  • Developing a Cement Tile Using Needle Waste 
    Gunawardena, K.L.R.T.; Vitharana, V.H.P. (University of Ruhuna, Matara, Sri Lanka, 2022-03-02)
    Needle waste is an unavoidable waste generated from textile industry. Since the reduced degradability, this type of waste may cause for severe environmental problems. Through this study needle waste converts into a ...
  • Development of sweet potato starch-based thin films to produce biodegradable packaging materials 
    Sasikala, K.L.N.S.; Kondarage, Y.G.; Senavirathna, H.V.H.H.; Diyabalanage, S.; Rodrigo, D. (Ruhuna Science Research Circle, Faculty of Science, University of Ruhuna, 2022-11-02)
    Starch-based bio plastics have been widely used because of their renewability, sustainability, and cost-effectiveness. However, due to the excessive water absorption and poor mechanical characteristics, native starch films ...
  • Preparation and characterization of geopolymer composite containing fly ash (FA) and rice husk ash (RHA) 
    De Silva, S.V.R.; Kondarage, Y.G.; Deemantha, M.B.A.; Pitawala, H.M.J.C. (Ruhuna Science Research Circle, Faculty of Science, University of Ruhuna, 2022-11-02)
    The construction material currently in use is Ordinary Portland Cement (OPC). Due to the drawbacks of OPCs, such as being an energy-intensive process and emitting large amounts of greenhouse gases, research into the use ...
