Concrete is resistant to moisture and durable, making it suitable for long-term use even in extreme environments. Concrete blocks, which are molded and cured in factories and then assembled on-site by stacking, are sometimes reinforced with steel bars to create retaining walls. They are also stacked between columns and beams to serve as partition walls that do not bear loads. Additionally, designs with hollow shapes are utilized as screen walls, adding patterns and decoration. We aim to not only use these concrete blocks as a motif for masonry walls but also to extend their use into furniture.
