Brief Overview 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.
NRC can be used for bedding mortars, renders, plasters, grouts, and slurry/bonding coats.
NRC has a better compatible strength with historic masonry and renders due to the special processing of the gault stone and the lower kiln temperatures used.
NRC is suitable for conservation and new build projects where characteristics such as breathability, flexibility and colour are important.
NRC can be blended with up to 2 parts lime; when mixed with the right aggregate it will produce a more flexible material with a vapour open quality which is similar to air lime.
NRC has a unique buff colour which, unlike other cements, does not produce any grey tones.
NRC is unique because it is cement without mineral or chemical additives to control the speed of set.
