Abstract:
Predictions of LC3 workability are important for field placements. It is understood that the rheological properties of LC3 are dominated by the composition and amount of calcined clay used. However, we lack an understanding on how other factors – including limestone particle size and gypsum addition rate - influence the rheology of LC3 incorporating different calcined clay contents. In this research, rheology of LC3 was related to hydration kinetics and microstructural evolution, obtained by isothermal calorimetry and in-situ XRD, respectively. The results suggest that rheology of LC3 formulations can be predicted by parametrized hydration kinetics, with an interaction term related to the LC3 composition.
