Ipomoea carnea (Besharam) which grows wild in India has been identified as a useful material for several applications including housing. Problems associated with this material for housing are listed and a study of the structure, properties, mechanical and thermal behaviour has been conducted. Ipomoea carnea is a ligno-cellulosic plant material with a measured tensile strength of the order of 15–25 MN/m2 and a high flexure strength. These results are discussed in terms of the cellulose contents and spiral angles of ligno-cellulosic materials. The width of the cells in Ipomoea is of the order of 40–50 ωm with a wall thickness of the order of 10 ωm; the length of the cells in the central part can be of the order of 250 ωm. The powder of Ipomoea carnea is stable up to nearly 200°C, above which it shows signs of degradation. Ipomoea carnea chips, and its powder mix and bond readily with polyester resin, cement and mud. Coating of cresote, polyester, cashew-nut shell liquid and copper were successfully applied on the surface of Ipomoea carnea. The tensile strength of polyester containing 3.68% vol. Ipomoea carnea powder was of the order of 22 MN/m2. The bond strength of Ipomoea carnea with mud plaster + 2.5% cement was good. The ultimate load bearing capacity of 2.5% cement stabilised mud plastered panel having 14% vol. Ipomoea gave a factor of safety of 3 for normal wind loading, indicating that it is a promising material for housing.
