Suitability of modified low carbon Roman cements for architectural restoration

Article is devoted to the investigation of suitability low carbon Roman cement for restoration and finishing works. The history development as a natural hydraulic binder, which was commonly used decorate building facades in 19th early 20th centuries, presented. properties mortars based on make it an excellent product architectural conservation, they are characterized by fast setting, high porosity typical lime mortars, resistance weather conditions, initial strength. At same time, due surface activity increased water demand cement, with age hardening, shrinkage deformations can develop, leads formation main cracks products. It shown that addition gypsum effective regulator setting time contributes increase strength paste. Analogs multicomponent binders modified plasticizing air-entraining additives
