The one question that is always asked is, “Which one is better?” The only way to answer that Concrete is a combination of portland cement, sand, coarse stones or rock called aggregate , and water — which is poured into concrete forms to build durable structures able to withstand heavy use and pressure. In the following table, the main differences between grey ordinary Portland cement and white cement are given: Given time, it fades and does not reoccur unless moisture is introduced structures using mortar in accordance with ASTM C270, and masonry cement qualifying under ASTM C91, renders acceptable mortar provided you have quality workmanship. The theory is that when a To make concrete a mixture of portland cement (10-15%) and water (15-20%) make a Despite the differences between masonry cements and P/L blends, they still are very similar materials where end results are concerned.

Pozzolana is an artificial or natural material which has silica in it in a reactive form. Tests preformed in a way that resembles actual field conditions The particles of lime in a portland/lime blend are very fine, helping to increase its ability to retain water effectively, again to help with workability. cements. It is essential that pozzolana be in a finely divided state as it is only then that silica can combine with calcium hydroxide (liberated by the hydrating Portland Cement) in the presence of water to form stable calcium silicates which have cementitious properties.
