摘要：Stucco monuments suffer from many causes of deterioration; one of these is the transformation of the gypsum content of stucco to anhydrite, which causes disintegration and the appearance of fine fissures that sometimes culminate in the complete loss of archaeological stucco material; this problem makes thinking of a new protocol for its treatment very urgent. So the research proposes using sulphate activators, which may lead to retransformation of anhydrite to gypsum and thus will participate in protecting our stucco heritage. Many parameters have been used; including XRPD analysis, XRF, FTIR, measurement of physical and mechanical properties, SEM and aging by sodium chloride. All results proved that sulphate activator solutions have the ability to retransform anhydrite to gypsum and to increase the mechanical strength of stucco material.
