Portland Cement-Lime Mortars for Conservation

2018-7-7  It is currently widely accepted that lime, rather than Portland cement (PC), should be used for the repair of historic fabrics as most historic mortars were lime based and properties of PC mortar such as strength, stiffness and permeability can be incompatible with historic stone and brick, with consequent damage to fabrics.

The Green Concrete of Ancient Rome - Conservation

2013-9-9  To make Portland cement, a mix of limestone and clays must be heated to 1,450 degrees Celsius. The Roman seawater concrete, by contrast, used lime mixed with volcanic ash, and the calcination of limestone occurs at about 900 degrees Celsius—requiring far less fuel to produce than Portland cement does. And the Roman concrete has withstood the ...
