With up to 20% pozzolana can increase the initial setting time. Compressive strength depends on pozzolana percentage and curing time. With Burnt Pozzolana and lime high compressive strength and increase in workability and setting time were noticed. Therefore natural pozzolana in Sudan can be used in concrete to replace the cement content. 2.
