Title:
SURFACE FINISH TIMING DETERMINATION METHOD
Document Type and Number:
Japanese Patent JP2018188810
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a practical surface finish timing determination method capable of determining whether or not a surface finish by a trowel of a concrete slab can be started, by a simple method at a low cost.SOLUTION: A surface finish timing determination method for determining a timing when surface finish of the concrete slab is performed after placing a concrete slab includes a dropping step of allowing the spheres of a predetermined mass to fall freely on the surface of the concrete slab, and a determination step of measuring the diameter of the concave formed on the surface of the concrete slab by the free falling spheres to determine the finishing time.SELECTED DRAWING: Figure 1
