An evaluation of life long fly ash based geopolymer cement and ordinary Portland cement costs using extended life cycle cost method in Australia

摘要

Numerous researchers focused on the life cycle costing assessment of procurement events for facilities and they have less concerned material and manufacturing costs, particular in cement industry, which has been identifying as one of the major air pollution sources, intensively used raw materials and energy in terms of cost. This paper adapted and extended the life cycle cost assessment including capital, maintenance, manufacture, material, disposal, environment and residue value based on 20 years life-long for evaluation fly ash based geopolymer cement and ordinary Portland cement manufacture. The outcome of production of fly ash based geopolymer cement is more expensive than ordinary Portland cement manufacture using proposed extended life cycle cost methods.
