Analysis of Sorghum Stalks and Fibres for use in the Production of Low-Cost Housing Bricks

Research into low-cost housing solutions, especially for low- and middle-income countries, has grown in recent years. Greater use of natural materials, both mineral and bio-based, offers opportunities for more affordable and sustainable materials and products. In this study, fibres and stalks from the sorghum plant have been investigated as potential additives in low-cost brick production. Analysis of the sorghum fibres and stalks has included microstructural examination using a scanning electron microscope and mercury intrusion porosimetry, together with tensile strength testing of fibres. Sorghum stalks and fibres were found to have comparable tensile strength to fibres currently used for brick production.
