Potentials of Dekina Cassava Peel Ash In Concrete Production

Abstract

Basic conventional building materials like cement and aggregates are becoming increasingly expensive due to high cost incurred in their processes, production and transportation. The utilization of locally available materials such as cassava peel ash that can either reduce or replace the conventional ones is being considered. Following review paper summarizes the mechanical and durability characteristics of cassava peel ash compared with ordinary Portland cement. The cassava peel ash was obtained by calcinations of cassava peel to 700oC temperature. The sample was investigated using XRS-FP Analysis, for evaluating the concentration of each component such as SiO2, Al2O3, Fe2O3, CaO, MgO, SO3, K2O Na2O and LOI. The phase composition, mechanical and durability properties evolution. The results reveal an oxide composition of 81.14% for the cassava peel ash. These analyses have shown that natural pozzolan based geopolymer has potential to be used as sustainable building materials. It was discovered that the cassava peel ash contains all the main chemical constituents of cement though in lower percentage compared with OPC which shows that it can serve as a suitable replacement if the right percentage is used.
