“…The mix design is derived from the input data, and the evaluator considers the calibration. In terms of calibrating the mix design, cement can be replaced with blast-furnace cement, ground granulated blast-furnace slag, or fly ash; the natural aggregate can be replaced with recycled aggregate [39].…”

An Optimization System for Concrete Life Cycle Cost and Related CO2 Emissions

et al. 2016

An optimization system that supports the production of concrete while minimizing carbon dioxide (CO 2 ) emissions or costs is presented that incorporates an evolution algorithm for the materials' mix design stage, a trigonometric function for the transportation stage, and a stochastic model for the manufacturing stage. A case study demonstrates that applying the optimization system reduced CO 2 emissions by 34% compared to the standard concrete production processes typically used. When minimizing the cost of concrete production was prioritized, the cost dropped by 1% compared to the cost of conventional concrete production. These findings confirm that this optimization system helps with the design of the concrete mix and the choice of a material supplier, thus reducing both CO 2 emissions and costs.
