Abstract: 
Reused construction systems are economical and environmentally friendly. However, such systems have not been developed yet for a practical stage. A reason for this situation is the bonding stress transmission method, such as welding in steel structures or adhesion between rebar and concrete in RC structures, is primarily used to connect members, and such method makes their reuse difficult. Therefore, we propose novel construction systems for “Complete Reuse using Ultra high performance-hybrid Fibre reinforced cement-based composites Blocks” (CR-UFB) that could be applied for a “jigsaw puzzle structure” because its high durability and high mechanical properties. In contrast to conventional designs, our system may enable buildings to consist only of an unbonded connection such a jigsaw puzzle without the need for reinforcing materials such as rebar, mortar or adhesives. As the first step, we experimentally investigated the mechanical properties in the connections and opened up the possibilities of the CR-UFB.
