Grout Sample Box, 4 Gang, package of 25

The Grout Sample Box has been proven to yield comparable compressive strength values to samples cast by the traditional ASTM C1019 method using concrete masonry units; but saves you time and money.

Slotted corrugation retains moisture and closely simulates CMU absorption rate. Single-use cardboard box acts as mold and transport container; it stores flat and takes seconds to put together for molding. Each box yields 4 consistent mortar specimens 3 in x 3 in x 6 in (7.6 x 7.6 x 15.2) cm.

Ships 25 boxes per carton.
