A study on properties of concrete with dry fly ash and fly ash slurry stored with stirring
Acta Polytechnica CTU Proceedings, 2022 In the evaluation of concrete sustainability, what constitutes "sustainable" to one region may vary from another. This often leads to methodological forms of uncertainties that makes the evaluation process more complex.
