Potentials of Balanite Endocarp Pod Ash as a Cement Replacement Material DOI:  https://doi.org/10.30564/jbms.v4i1.4800 Abstract The exponential growth of agricultural wastes such as Balanite seed pod has resulted in waste management issues and finding alternatives through waste recycling is an interesting area of research. Balanite seed pods were collected in Yobe state, washed, dried, crushed. Balanite endocarp pod ash (BEPA) was calcined at 600 °C for 3 hours in a muffle furnace and the biomass was characterized with X-ray fluorescence spectrometer to determine its chemical composition. The analysis showed that the ash composed of silica, alumina and ferric oxide (74.24 wt.%) indicated a strong pozzolan based on American Standard. The BEPA possessed a high loss on ignition of 8.24 wt.% owing to the presence of unburnt carbon in the ash. The ash obtained was sieved with 75 µm sieve and cement was replaced with ash between 2.5 wt.% ~ 12.5 wt.% at interval of 2.5 wt.% to assess its ...

Influence of Selected Curing Techniques on Compressive Strength of Concrete From Palm Kernel Shell Ash and Ordinary Portland Cement DOI:  https://doi.org/10.30564/jaeser.v4i3.3315 Abstract This paper discusses the findings of an experimental study on the effect of various curing procedures on the compressive strength of concrete produced by partially substituting portland cement with Palm Kernel Shell Ash (PKSA). Palm kernel shell ash was utilized in a 1:2:4 mix ratio as a partial substitute for ordinary Portland cement (OPC) at percentage levels of 0%, 10%, and 15%. River sand with particles passing a 4.75 mm BS sieve was used, as well as crushed aggregate with a maximum size of 20 mm, and palm kernel shell ash with particles passing a 212 μm sieve. The compressive strength of the test cubes (150 mm x 150 mm x 150 mm) was determined after 7, 28, and 56 days of curing. The results demonstrated that test cubes containing Palm kernel shell ash developed strength over a longer curing ...
