31/08/2020· Pozzolana is a natural or artificial siliceous material in a reactive form. It may be further discussed as siliceous and aluminous material which itself possesses little, or no cementitious properties but will in finely divided form and in the presence of moisture, chemically react with Calcium Hydroxide, Ca(OH) 2, (the unwanted by-product of cement hydration) at ordinary temperature to form

Pozzolana hydraulic cement Britannica

Pozzolana, also spelled pozzuolana, or pozzolan, hydraulic cement discovered by the Romans and still used in some countries, made by grinding pozzolana (a type of slag that may be either natural—i.e., volcanic—or artificial, from a blast furnace) with powdered hydrated lime.Roman engineers used two parts by weight of pozzolana mixed with one part of lime to give strength to mortar and

Portland Pozzolana Cement (PPC): Advantages and Uses

18/12/2017· The above advantages of Portland pozzolana cement have been attributed due to the slow conver­sion of calcium hydroxide Ca(OH) 2 in the hydrated cement paste into cementitious product. In one of the recent studies in an ordinary Portland cement paste only 20% calcium hydroxide was found after 1 year hydration where as in a similarly hydrated paste containing 30% pozzolana, only 8.8%

Pozzolanic cements ScienceDirect

Hardening of pozzolanic cement pastes can result from the reaction between pozzolana and the lime that is added to the mix as hydrated lime or is produced following hydration of portland cement silicates. The pozzolanic reaction does not alter cement clinker hydration; it complements and integrates the hydration process because it results in a lower portlandite content and an increase in

History of cement

The Romans found that a cement could be made which set under water and this was used for the construction of harbours. This cement was made by adding crushed volcanic ash to lime and was later called a "pozzolanic" cement, named after the village of Pozzuoli near Vesuvius. In places where volcanic ash was scarce, such as Britain, crushed brick or tile was used instead. The Romans were
