Basalt has excellent compressive and flexural properties, as well as good wear resistance and low water absorption. It is also a very good building decoration material, which can be widely used for indoor and outdoor decoration. It is mainly used as outdoor stone, and its natural color can coordinate well with the surrounding landscape. It is very suitable for outdoor landscape construction, especially for the selection of floor stone. However, as mentioned earlier, basalt is prone to forming hexagonal columnar joints and is brittle, so the stone blocks are generally not large and lack large materials, making it difficult to produce large-sized slabs.
