<P>PROBLEM TO BE SOLVED: To provide a circulation type building material which can be used as a building material by filling a low alkaline cement composition between bamboo joint walls to impart sufficiently durable strength as a building member, and by opening a mortise on a joint between each joint of members and using a curl plug and a wood screw, and which can be dismantled easily and reused as a fertilizer or an aggregate when being crushed. <P>SOLUTION: The low alkaline cement composition contains light-burned magnesia, silica fume and mountain sand as main components, and a composition obtained by adding a phosphate to a reactant and kneading it with water is filled into a space between bamboo joint walls, to thereby become usable as a building material requiring strength capable of showing a remarkably higher numerical values in bending strength or compressive strength in comparison with an unfilled bamboo material. Further, a mortise can be opened on a joint between each low alkaline cement composition-filled bamboo composite member, and a curl plug and a wood screw can be used, to thereby become easily fixable and easily detachable when being detached, and to obtain a bamboo composite member as a circulation type building material which is easily reusable and sortable. <P>COPYRIGHT: (C)2012,JPO&INPIT |
