Hydration Behavior and Cementitious Properties of Calcium Carbonate-aluminate Minerals Composite

Abstract

The purpose of this research is to investigate the hydration behavior and cementitious properties of the mixture of calcium carbonate and aluminate, and to explore whether it can be adopted as a new low-carbon cementitious material. The composite system of calcium carbonate and aluminate minerals is studied by measuring the component of hydration products, the hydration heat, setting time and compressive strength. The results prove that the composite system has certain cementitious properties and is feasible to prepare new low-carbon cement.
