Abstract

Recent investigations demonstrated that the processes of hydrating tricalcium silicate pastes are made favorable by the addition of certain quantities of dicalcium silicate. Optimization of these processes was reflected in the increased compressive strength of corresponding mortars, suggesting an alteration to the hydration products affecting the bulk properties. The microstructure of these mortars was investigated here using scanning electron microscope analysis with backscattered electron and X-ray imaging. A clear link between the paste composition and development of microstructure and product formation affecting bulk properties is demonstrated.
