Resin conerete is made by mixing resin and inorganic filler at a construction site and is applied to the floor with a trowel. Resin concrete has various features,including chemical resistance and mechanical strength, that derive from features of its reactive resin component, and is used for various purposes as a durable floor material. However, surface irregularities caused during troweling bend to remain, so improved leveling of the finished surface is required. We estabhshed a quantitative evaluation method by using a leveling tester to evaluate surface irregularities caused by troweling and applied the parameter design techniques of quality engineering. As a resulL, a 14 to 17 db improvement in leveling was obtained and troweling efficiency was also improved. The improvement in troweling efficiency permitted the use of only one grade of filler instead of the two grades that had been used selectively before. The fact that these results were obtained in a short period of time, which would have been difficult with conventional methods, shows that quality engineering can be efficiently applied to formulation design for materials.
