Reinforcement of the terracotta sculpture by geopolymer composite

Presented paper opens the possibility to use the geopolymer binder as fixing and joining material in restoration of the valuable historical objects. Special geopolymer composite was prepared to match the structure and color for reinforcement of the terracotta Baroque statue. The application in the cavity of the sculpture creates system of consolidating rims and ribs. The geopolymer technique was applied only on the unseen part of the statue, which ensured the stability and durability of the object without disrupting the aesthetics for the viewer. The exterior modulation and final restoration was carried out using classic technologies, specifically calcite-bonding agents, and is not the subject of this paper.
