It was observed from the analysis of the results of the experiment that 5 - 10% of the local gin also called 'ogogoro' increases the compressive strength of concrete and acts as an admixture (accelerator and retarder at various concentrations) in both concrete and mortar respectively. http://pubs.sciepub.com/ajcea/5/6/4/ajcea-5-6-4.pdf admixture compressive strength concrete flexural strength local gin mortar setting time split tensile strength water absorption
