Abstract:The paper discusses advantages, particularly with respect to CO2 emission reduction, of the replacement of relatively large fractions of Portland cement in concrete mix designs utilized in pavements and structures, with industrial byproducts and natural materials. It further addresses methods of quality control for such materials.
