Presence of aragonite–vaterite–calcite: Polymorphs of CaCO₃ in the ancient lime works of Alampur.

Occurrence of polymorphs may be either due to the biotic mineralization process or by self healing of lime in wet and dry cycle in presence of Mg.

Sub-angular to sub-rounded, medium to low maturity sand and coarse silt aggregates were detected in the plaster.

This study is crucial in evaluating the compatible materials in the conservation of built heritage.
