|---|---|
| Description | कंक्रीट खंड (Concrete Block), a precast masonry unit [1], comprises cement (binder), aggregates (स्थूल समुच्चय), and water. Its composition mirrors traditional *vajralepa* (वज्रलेप) techniques, albeit with modern materials. Compressive strength ranges from 3-30 MPa, density from 600-2400 kg/m³, and water absorption from 5-20%. Thermal conductivity is 0.3-1.0 W/mK. Sourced from quarries (खदान) and cement factories across the Indian subcontinent, aggregates historically included river sand and crushed stone. While not directly analogous to ancient brickwork, its use echoes the scale of Mauryan and Gupta-era construction. Modern applications include load-bearing (भारवाही) and non-load-bearing (गैर-भारवाही) walls. Conservation requires understanding cement hydration products and aggregate reactivity. Restoration on heritage sites demands careful matching of color and texture to preserve aesthetic integrity. Durability depends on mix design and environmental exposure, requiring periodic inspection and repair to mitigate cracking and spalling. |
