Grout Volume Change

The micrometer bridge set measures grout volume change.  The set holds one cylinder to permit repeated volume change measurements without moving or disturbing the specimen.  The test method covers the determination of grout volume change (change in height) of the specimen from the time of molding until the mixture is hardens.  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.
