The Effects of Sugar Cane Bagasse Ash as Supplementary Cementitious Material in Production of Concrete

ABSTRACTSugarcane Bagasse is the fibrous residue leftover when sugarcane is squeezed for its juice. Bagasse ash is obtained by subjecting Bagasse to calcinations using furnace. This work is aimed tat using Bagasse Ash as a replacement in the production of concrete.The bagasse was collected from dumped in a market in Kano and thereafter sun-drie to eliminate any trace of moisture. It was then taken to the blast furnace for calcinations(controlled burning) at a temperature of 1250OC for ...

Investigation of the Spatial and Temporal Variation of Sediment Yield and Surface Runoff in Offa Watershed Kwara State

ABSTRACTIn this research, an hydrological modelling tool, soil and water assessment tool (SWAT) used to investigate the spatial and temporal variation of sediment yield in a watershed. The model was run for 31years using spatial data such as Digital Elevation Model, soil map, land use and precipitation, wind and solar radiation. The results showed that the maximum value of surface Runoff was estimated as 19100.034mm in the year 2005 while the minimum surface Runoff was 1000.671mm in th...
