<P>PROBLEM TO BE SOLVED: To provide an earthquake-resistant slit which solves problems in returnable deformation, heat insulation, fire resistance, and the like at once. <P>SOLUTION: An earthquake-resistant slit material 13 which is disposed between wall bodies or between a wall body and a column body for earthquake-resistant slit construction during cement placement for a building is made of a cured molded object of a slurry composition composed of a mixture of cement (hydraulic setting inorganic binder), a foam bead (spherical body) of synthetic resin, and other secondary materials. The cured molded object has 83% or higher returnable deformation in a compression test according to the performance test method of a slit material in the quality determination standard for materials (May 2008 edition) established by Urban Renaissance Agency. <P>COPYRIGHT: (C)2013,JPO&INPIT |
