Establishment of Relationships Between Compaction Parameters and Oxides Composition of Industrial Waste Materials

Abstract

Research regarding the effectiveness of using industrial wastes as a stabilizer is rapidly increasing. Industrial wastes, generally, constitute with chemical and mineralogical compositions in disproportional quantity that varies from minor to remarkable. At this juncture, it is essential to have a better understanding on the suitability of waste materials to be used as local construction material in a way to minimize the amount of waste to be disposed of, and thereby, reduce environmental pollution. This paper attempts to establish correlations of the compaction parameters of waste materials with their oxides composition. Oxides contents such as SiO2, Al2O3, CaO, and Fe2O3 are considered in the study. In general, it was observed that maximum dry density increases with an increase in calcium and ferric oxides and decreases with an increase in silica and aluminium oxides. With regard to optimum moisture content, it is noticed an increase of it with an increase in aluminium and silica oxides and decrease with an increase in calcium oxide. Out of these four main oxide compositions, the impact of calcium oxide on both maximum dry density and optimum water content is found predominant.
