| Description | कच्ची ईंट (kacchi int, unfired brick), also known as धूप में सुखाई ईंट (dhup mein sukhai int, sun-dried brick), is a traditional Indic construction material composed primarily of clay-rich soil. Its geological origin lies in alluvial deposits common across the Indian subcontinent. The chemical composition is dominated by silica, alumina, and iron oxides, with organic matter from plant fibers like straw often added as a binder [1]. Processing involves mixing clay with water and aggregates, molding into rectangular shapes, and sun-drying. Shrinkage (5-10%) during drying is a critical consideration [2]. Compressive strength ranges from 0.5-1.5 MPa, with a density of 1.6-1.8 g/cm³ and thermal conductivity of 0.4-0.6 W/mK. Historically, कच्ची ईंट was extensively used during the Maurya and Gupta dynasties for non-load bearing walls and infill. Traditional quarries (खदान, khadaan) provided the raw materials. Conservation of heritage structures built with कच्ची ईंट requires careful attention to moisture control and erosion mitigation. Restoration often involves using locally sourced clay with similar properties to the original material [3]. |
