Composition and Microstructure of Cement-Like Materials Synthesized by Solution Combustion Technique

Abstract:

Massive production of Portland cement through mining process imposes detrimental effects on environment. Utilization of industrial and agricultural wastes as alternative raw materials for cement production, thus, has a pronounced positive impact on human quality of life. This study aimed at synthesizing constituents that exist in Portland cement by the solution combustion technique. Cockleshell, rice husk ash, and alumina wastes were used as initial reagents for the synthesis. Compositional analysis of the synthesized powders exhibited desired phases of dicalcium silicate, tricalcium silicate, and tricalcium aluminate. Compositional and microstructural analyses of the specimens cast from combusted powders revealed similar features compared with Portland cement. Ettringite, calcium hydroxide, and calcium silicate hydrate were prominent phases observed from both compositional and microstructural analyses.
