Highlights Alite–ye’elimite cement clinker containing ye’elimite is synthesized by annealing. Annealing promotes the reformation of ye’elimite with C3A and C$ reaction. The clinker shows expansion until 150days and high early strength. Ye’elimite in the clinker modified the strength development and expansion behaviour. AFt is one of the main products in the hydrates.
Abstract An expansive high early strength alite–ye’elimite clinker containing 4.8% ye’elimite was synthesised by annealing without addition of mineralizer into the raw meal. The reformation of ye’elimite was achieved by C3A reacting with C$ in clinker. The microstructure of the paste was characterised by SEM, MIP and N2 adsorption/desorption. DSC-TG and XRD were used to investigate the hydration products of the paste. Mortar tests on the clinker yielded values of 30.0MPa, 42.3MPa and 55.8MPa at 1, 3 and 28days, respectively. Due to the presence of AFt in the hydrated paste, the expansive behaviour resulted in a reduction in the total pore volume by 29–62% (0.01–10μm), but there were more mesopores (2–50nm) due to the crystalisation of AFt. The linear expansion converged after ∼150days with maximum expansion of 0.136%.
