Grout Volume Change

The micrometer bridge set measures grout volume change.  It is designed to hold one cylinder to permit repeated volume change measurements without moving or disturbing the specimen.  The test method covers the determination of change in height of the specimen from the time of molding until the mixture is hard.  It measures volume change due to hydration, settlement, evaporation, and other physical and chemical effects. The set includes the micrometer bridge, depth gauge, tapered cylinder mold, tamping rod, glass plate, and 3 lb weight.  The products that make up the micrometer bridge set are also available to be purchased separately as replacement parts.
