Abstract:

The results of the study indicate that the 24-hr compressive strength of 2-in. cubes of 11 cement-Ottawa sand mortar may be used to show whether a cement as manufactured contains sufficient SO3. If insufficient calcium sulfate were added during manufacture to provide the optimum amount of SO3, the optimum amount can be determined by addition of successive increments of gypsum to the cement until the maximum strength is reached, as indicated by compressive strength tests of 2-in. cubes at 24-hr. age.
