|---|---|
| Description | पूर्वनिर्मित फलक (Poorvanirmit Falak), or precast panel, are composite construction elements primarily composed of concrete [1]. Their composition typically includes cement (often sourced from limestone quarries in regions like Rajasthan), aggregates (sand and crushed stone from riverbeds or mines), and reinforcing steel. Historically, similar concepts using stone slabs, *shila khandas*, were employed in Indic architecture, notably during the Mauryan and Gupta periods. Modern precast panels offer controlled curing environments, enhancing compressive strength (30-80 MPa) and density (2300-2500 kg/m³). Durability is influenced by aggregate type, cement composition, and environmental exposure. Conservation involves assessing material degradation (e.g., *kshara* - alkali attack) and implementing appropriate repair strategies. Restoration of heritage structures using precast elements requires careful matching of color, texture, and *rupa* (form) to the original materials. Consideration of *vastu shastra* principles in panel design is also relevant in certain contexts. The panels are used for walls, cladding, and façade elements. |
