The Roman Cement or Natural Cement is a natural hydraulic binder, manufactured from only one raw material. It is the result of burning process of marly limestone, with the regular composition and very finely ground, between 500 and 1200° C.
Fields of use: plasters, mortars, etc.
Roman Cement is used in the restoration of historical monuments, in quick-setting and hydraulic works. It is also used to make prefabricated mold elements: moldings, friezes, frames, etc. in the recovery of artificial stone buildings built between the mid-nineteenth and post-war years. Natural Cement mixed with air lime or with natural hydraulic lime allows to make plaster mortars, rustic-looking finishes, stuccoes and, again, quick-setting fluid injection mortars. By virtue of its natural origin, it is perfectly suited to the realization of green building works, straw bale houses, raw earth and hemp.
