ABSTRACT
Lime was used as a binding agent for brick and stone by the ancient civilisations throughout the world. The concept was brought to Britain in the first century AD by the Romans, who used the material to produce lime mortar. Outside Britain, the Romans frequently mixed lime with volcanic ashes, such as pozzolana from Pozzuoli in Italy, to convert a non-hydraulic lime
Introduction In its broadest sense, the term cement refers to materials which act as adhesives. However, in this context, its use is restricted to that of a binding agent for sand, stone and other aggregates within the manufacture of mortar and concrete. Hydraulic cements and limes set and harden by internal chemical reactions when mixed with water. Non-hydraulic materials will only harden
Britain, lime was usually mixed with artificial pozzo - lanas, for example, crushed burnt-clay products, such as pottery, brick and tile. In the eighteenth century, socalled Roman cement was manufactured by burning of the cement stone (argillaceous or clayey limestone), collected from the coast around Sheppey and Essex.
