... to the enhancement of CBC. At high pH value, OH⁻ competes with Cl⁻ to more easily bind with the AFm phase, which is not conducive to chloride binding. However, when the pH value is extremely low, Friedel’s and Kuzel’s salts tend to be unstable, resulting in the release of the chemically bound...

... to retain a higher ettringite content in cement pastes at later hydration time. With calcite powders contained in EVA as the anti-blocking agents, the formation of two AFm phases, hemicarboaluminate and monocarboaluminate, is promoted by EVA after 3 d of hydration. Accordingly, more types of calcium...
