Production and Characterization of Wood Ash Pozzolan of Melina and Cashew Tropical Woods

Abstract

In an attempt to find an alternative binding material for construction industry, this study considered the use of wood ash from two different hardwoods namely: Melina wood ash and Cashew wood ash as a pozzolan in cement production. The study investigates the chemical composition (silica (SiO2), aluminum oxide (Al2O3), ferric oxide (Fe2O3), calcium oxide (CaO), magnesium oxide (MgO), sulphur trioxide (SO3), sodium oxide (Na2O) and potassium Oxide (K2O)) of the ashes and the clinker.
