Question 1

What is संपीडित मृदा (Rammed Earth)?

Accepted Answer

संपीडित मृत्तिका (Saṃpīḍita Mṛttikā, Rammed Earth) is a composite material prevalent in Indic architecture since the Indus Valley Civilization [2]. Composed of *mṛttikā* (मृत्तिका, soil), gravel, and sometimes lime, sourced from quarries and riverbeds across Rajasthan, Gujarat, and the Deccan Plateau, it served as a primary structural element [3]. The Mauryan and Gupta Dynasties extensively used it for load-bearing walls and foundations.

Physical properties include a dry density of 1.8-2.2 g/cm³ and compressive strength of 2-10 MPa [3]. Processing involves compacting the mixture within formwork, achieving high thermal mass. Thermal conductivity ranges from 0.8-1.5 W/mK. Durability depends on soil composition and compaction techniques like *kūṭī hu'ī miṭṭī* (कूटी हुई मिट्टी, compacted earth) [1].

Conservation at heritage sites in Uttar Pradesh and Maharashtra necessitates analyzing the original *mṛttikā* composition. Restoration considers porosity (10-25%) and thermal diffusivity (0.4-0.6 mm²/s). Traditional *dābita mṛttikā* (दाबित मृत्तिका, compressed earth) techniques are crucial for structural integrity [1].
