This work investigates the possibility of using corn cob ash (CCA) as a soil stabilizing agent in pavement construction with a view to curbing the indiscriminate dumping of corn cob in the environment, enhancing the value of an otherwise waste product and subsequently increasing the worth of the corn plant to the rural farmer. Corn cob was obtained from Maya, a rural community in the derived savannah agro-ecological zone of South-Western Nigeria, and burnt to ashes of pozzolanic quality. Reddish brown silty clayey sand material, characterized as an A-2-6 (3) material and locally recognized as laterite was obtained from a borrow pit in Abeokuta and subjected to physical characterization tests according to BS 1377: 2000. The soil was subsequently mixed with CCA in varying percentages of 0%, 1.5%, 3%, 4.5% and 6.0% and the influence of CCA on the soil was determined for Atterberg Limits, Compaction Characteristics, CBR and the Unconfined Compression Test. The result shows that with increasing addition of binder from 1.5% to 6.0%, Maximum Dry Density progressively declined while the OMC steadily increased. For the CBR, the maximum positive impact was observed at 1.5% CCA addition with a value of 85% compared to the control value of 65%, but declined steadily thereafter with increasing addition of CCA, while that of soil-cement continued to increase with increasing addition of cement beyond 1.5% though at a slower rate. Similar behavior was observed in the UCS values for the soil-CCA mix, increasing from a control value of 0.4 MN/m2 to 1.0 MN/m2 at 1.5% CCA and declining thereafter. The paper concludes that the corn plant is valuable beyond the kernel and the proper harnessing of the cob as a fuel whose ash is subsequently recovered for use for soil stabilization purposes will widen the scope of post harvest economic activities and move the country towards the attainment of the objectives of the Millennium Development Goals of eradicating extreme poverty and achieving environmental sustainability. The paper calls on government to promote the recovery this biomass waste ash in the corn producing regions of the country as this would enhance the worth of the agricultural value chain to the farmer.
