"rammed earth"的定义和意义

What is "rammed earth"?

Rammed earth is a sustainable building technique that involves compressing a mixture of soil, sand, and gravel into forms to create solid walls. This method uses layers of earth that are compacted using heavy machinery or manual tools to achieve a dense and durable structure. Rammed earth walls are known for their thermal mass, which helps regulate indoor temperatures, and their natural appearance, which blends well with the environment. This construction technique is often used in eco-friendly buildings, as it utilizes locally sourced materials and has a low environmental impact. Properly constructed rammed earth walls can provide excellent insulation and resistance to fire and pests.
