What Defines Raw Earth in Building?
When we talk about raw earth in the context of construction, we're essentially referring to a mixture or a finished material that comes from unbaked earth. This means the soil, clay, and sand components are used just as they are found, or perhaps with a little bit of water and mixing, but without undergoing any high-temperature firing processes, like what happens with bricks or ceramics. It’s a natural material, very much a blend of moist clay and sand, that is shaped and allowed to dry and harden naturally, so.
A really important distinction is that raw earth materials are not typically mixed with hydraulic binders. These binders, like cement, create a chemical reaction when mixed with water to harden, and they are quite energy-intensive to produce. Raw earth, by contrast, relies on the natural cohesive properties of clay particles to bind the material together as it dries. This makes it, in a way, a truly natural and unadulterated building component, which is pretty cool.
This approach to building offers a completely natural, contemporary building material.
