Rammed Earthとは 意味・読み方・使い方

Rammed earth, also known as taipa (Portuguese), tapial (Spanish), pisé de terre or simply pisé (French), is a technique used in the building of walls using the raw materials of earth, chalk, lime and gravel. It is an ancient building method that has seen a revival in recent years as people seek more sustainable building materials and natural building methods. Rammed earth walls are simple to construct, incombustible, thermally massive, very strong and durable. However, they can be labour-intensive to construct without machinery (powered rammers), and, if improperly protected or maintained, they are susceptible to water damage. Traditionally, rammed earth buildings are found on every continent except Antarctica, from the temperate and wet regions of northern Europe to semi-dry deserts, mountain areas and the tropics. The availability of useful soil and a building design appropriate for local climatic conditions are the factors which favour its use.
