The Memory of Rock: Understanding Rammed Earth - The Science, Performance, and Contemporary Case (Paperback) (ISBN-13: 9789359873664)

Rammed earth is dispersed rock, compressed back toward the state it came from. This book explains why it works - not how to build with it, but the science behind every property that makes the material worth building with.

Twelve chapters cover the full picture. The geology of soil and what compression actually does at the particle level. The narrow moisture window that separates a strong wall from a failed one. Thermal lag - how a 300-millimetre wall delays heat by 8 to 12 hours, turning a 24-hour climate cycle into passive cooling. Humidity regulation through hygroscopic clay that buffers indoor moisture without mechanical systems. Acoustics - mass that blocks, layers that dissipate, surface texture that absorbs. Fire resistance from minerals that have nothing left to give to combustion. Structural logic - compression, load paths, ring beams, and a 100-foot tower in Pakistan that proves the principle at scale. Durability measured in centuries, not decades, with one condition: manage water. Embodied energy at a fraction of concrete's cost to the planet. The contemporary case for a material whose moment has returned. The honest limitations - where it doesn't work and why. And finally, the whole building as one integrated system where foundation, wall, roof, and drainage work together or not at all.

Written by a practitioner who consults, teaches and builds. Science-grounded. Direct. Just what the material does and why it matters now.
