Grout Volume Change
Showing the single result
The micrometer bridge set measures grout volume change. Â The set holds one cylinder to permit repeated volume change measurements without moving or disturbing the specimen. Â 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. Â 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. Â The products that make up the micrometer bridge set are also available to be purchased separately as replacement parts.
