Cementless Compositions for the Restoration of White Stone Based on Lime Binder and Silicon Dioxide

Researchers have developed cement-free compositions for restoring white stone, combining lime and silicon dioxide with chemical additives to enhance adhesive and strength properties. The addition of white soot (silicon dioxide) increases adhesive strength by 1.5 times and compressive strength from 10.6 to 15.6 MPa, surpassing the strength of composites without white soot. These compositions exhibit homogeneous structures compatible with white stone and high adhesion levels, making them promising for the restoration of architectural monuments like those in the White Monuments of Vladimir and Suzdal. The study used modern equipment at the BM Department of VlSU to test these compositions, confirming their phase composition similarity to white stone through XRD, optical microscopy, and SEM analysis.
