Kinetics of enforced carbonation of cement paste

Cement and Concrete Research, 2020
The carbonation mechanisms of ground, hydrated cement pastes that mimic recycled concrete fines are investigated under direct wet carbonation. The carbonation is a sequential processes including dissolution of the hydrates, transport of the dissolved ...

Interfacial adhesion mechanism between organic polymer coating and hydrating cement paste

Cement & Concrete Composites, 2021
Surface coatings have proved to be one of the most effective methods to protect the concrete structures in aggressive environments. However, coating the structures with polymer after 28 days of curing/hydration to get the best interfacial performance has

High strength cement pastes

Journal of Materials Science, 1985
Etude des reactions chimiques dans les ciments a haute resistance (ciments MDF) en considerant en particulier l'interaction ciment-polymere. L'addition de faibles teneurs (1,6%) d'acetate/alcool de polyvinyl au ciment alumineux Secar 71 retarde sensiblement les reactions normales d'hydratation.

Premixed calcium–phosphate cement pastes

Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2003
AbstractA self‐hardening calcium–phosphate cement (CPC) containing Ca4(PO4)2O and CaHPO4 has been shown in clinical studies to be efficacious for repairing bone defects. This and several other similar CPCs harden in 10 min with the use of a phosphate solution as the liquid and form hydroxyapatite (HA) as the product.
