Abstract
There is a quest and a sustained interest in environmentally friendly and sustainable building materials, for farm structures, as well as for general building construction, due to the availability of suitable industrial materials, by-products and wastes, to which additional value can be provided in their utility and management. The suitability of using wood shavings as partial replacement for fine aggregate in concrete production, with cassava starch and sodium chloride (NaCl) as admixtures, was investigated in this study. The concrete was produced with a mix ratio of 1:2:4, and partial replacement of the fine aggregate with wood shavings, at the rate of 0%, 1.25%, 2.5%, 3.75%, 5%, 6.25%, and 7.5% (wt. of fine aggregate). Furthermore, cassava starch (2% by weight of the cement) and NaCl (1% by weight of the cement) were used as admixture. Results obtained from the slump and compression tests depicted that, the slump of the fresh concrete and the compressive strength of the hardened concrete decreased non-linearly as the volume of wood shavings increased from 0% to 7.5%. The findings of this study revealed that both the cassava starch and NaCl increased the slump properties of the fresh concrete, and the compressive strength of the hardened concrete, irrespective of the volume of wood shavings incorporated. Additionally, the results depicted that the hybridized concrete produced with wood shavings, cassava starch and NaCl, had a higher compressive strength, when compared to the hybridized concrete produced with wood shavings and cassava starch only. Results obtained from this study had affirmed that low volume of wood shavings, cassava starch and NaCl can be used for the production of plain concrete for farm structures, mostly in areas where metallic reinforcement materials are not required.
