Abstract
Carbonatable calcium silicate-based cements and concretes are presented, which result in concrete compositions that have an improved aesthetics. A cement product includes a plurality of particles of a carbonatable calcium silicate cement and a first additive; wherein, the first additive is a hydrophobic organic acid, or a salt thereof, or a silane, or a polysiloxane.
Claims21
A non-hydraulic cement product comprising:
- a plurality of particles of a carbonatable calcium silicate cement, the calcium silicate comprising one or more discrete calcium silicate phases selected from CS (wollastonite or pseudowollastonite), C3S2 (rankinite), C2S (belite, larnite, bredigite), and an amorphous calcium silicate phase at about 30% or more by mass of the total phases;
- a first additive and a second additive;
- wherein, the first additive is a hydrophobic organic acid, or a salt thereof, or a silane, or a polysiloxane, and the second additive is an organic molecule with at least one primary, secondary or tertiary amine group.
