Natural Roman Cement 18kg - London LimeNatural Roman Cement Data Sheet
In 1796 the Reverend James Parker Patented Roman cement which became highly desirable for its long term durability. After 1824 Roman cement declined due to the introduction of Portland cement which, in the present day, is burnt at fusion temperatures and can have some undesirable effects on historic buildings.
NRC has a better compatible strength with historic masonry and renders due to the special processing of gaultstone and the lower kiln temperatures used.
Please note bags are dated with manufacture date. It is known that NRC has a considerably longer shelf life than other cements.
