FLOOR STRUCTURE AND ITS CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To obtain a construction method for acquiring a floor structure with a surface having excellent horizontality even at a place and under a construction condition difficult to obtain the floor structure with the surface having excellent horizontality by the construction of slurry as a self-fluid hydraulic composition.

SOLUTION: The construction method for the floor structure includes a process forming a primer layer by coating and drying a primer on the top face of a floor foundation and a process forming a slurry (a) cured-body layer by placing and curing slurry (a) prepared by kneading water and a self-fluid hydraulic composition (a) having a flow value of 190 mm or larger and a Shore hardness of 30 or lower after 2 hours on the top face of the primer layer. The construction method for the floor structure further includes a process forming a slurry (b) cured-body layer by placing and curing slurry (b) prepared by kneading water and the self-fluid hydraulic composition (B) having the flow value of 190 mm or larger on the top face of the slurry (a) cured-body layer.
