In this context, “green” refers to concretes made with supplementary cementitious materials (SCMs) replacing varying amounts of portland cements to reduce the carbon footprint. Replacing large amounts of portland cement with SCMs can result in slower concrete setting and slower strength gain at both early and later ages. This research explores the relation between cylinder strengths and core strengths for low-cement content concretes.
