Grout cube strength testing

[rchanke]

Unconfined compressive strength testing of 2-inch cubes has been specified to follow ASTM C 942. What is the primary difference, if any, than testing to ASTM C 109? The question is in terms of curing, loading and breaking, nothing to do with casting and/or preparation of the grout cube.

Are you sure ASTM C942 is current? -- I am an ASTM memebr but could not acess to that standard (ASTM C942-99) and got a message that it was replaced/obsolete.

You may want to check to see if it was replaced by ASTM C109.
