Description
Summary:Most heritage monuments in India are made of stones, representing the rich cultural traditions of the region. Due to human interventions and natural causes these monuments are undergoing deterioration and need effective intervention. The weathering of stone monuments can be attributed to stone characteristics and also to the environment. This study attempts to investigate and assess extent of deterioration in two monuments, Khidrapur temple and Panhala Fort. Engineering properties and chemical composition of stones were determined. XRD analysis revealed the presence of minerals, pyroxene and olivine. SEM images show the formation of detritus minerals indicating the intrinsic weathering of rock. These studies reveal that agents of weathering have deteriorated the building stones from outside and inside also. Micro structural analysis also helped to identify the intrinsic characteristics of stone, which will aid in formulating preservative treatments and procedures. This study forms a base for sustainable conservation of these heritage monuments. The outcome of the study will be applicable for determining conservation strategies for the monuments built in basalt and laterite.
