Estimating the Cost-Competitiveness of Recycling-Based Geopolymer Concretes

چکیده
The cement industry is a major contributor to greenhouse gas emissions on global scale. Consequently, there has been an increasing interest, in both academia and business, low-carbon concretes which Ordinary Portland Cement (OPC) partially or fully replaced with industrial side streams. However, the realization of environmental benefits such materials depends how competitive they are construction market, where low costs factor. This not straightforward, as many types exist. Raw material prices vary, can be influenced by governmental regulations via carbon pricing. study presents case estimating cost four different geopolymer compositions footprints, considering raw price variability potential impact regulation (carbon price). demonstrates mix comparisons made openly systematically. results imply that pricing, at rates currently applied, does significantly change difference between traditional concretes. Instead, cost-competitiveness heavily type availability critical
