Description
Victoria Shvetsova and co-authors study two additives in a fast-setting blended cement: sodium citrate and a PCE plasticizer. The binder mixes Portland cement with a tenth calcium aluminate cement, giving quick set and high early heat. Each additive alone is known, but their combined and sequenced use was unmapped.
Their 2024 study tracks heat flow, phase makeup, microstructure, and the strength of fine concrete as the additives enter together or in turn. Citrate reshaped the new crystal phases and slowed the main silicate's hydration several fold, while speeding other clinker parts early on. Timing the plasticizer against the citrate changed the outcome again. The results guide mix designers who need speed without losing control of the cure.
