Correct Answer:
Option A - Tetra calcium alumina ferrite (C4AF) (8%)–
• It has the poorest cementing value but it responsible for long term gain of strength of the cement. It is responsible for flash setting.
• Produces little strength and is dark in colour usually very low percentage in the cement in white and off-white cement.
