WebGrout should be sampled by a qualified technician. A minimum bulk sample size of ½ ft³ (0.014 m ) is required for slump and compressive strength tests (ref. 3). Two or more grout portions are taken at regularly spaced intervals during grout discharge, and are then combined to form a bulk sample. No more than 15 minutes should elapse between ... WebDS - Dry Strength (kgf/cm2) Test. Dry strength is measured by supporting a bar on two points and applying an increasing force from above at the mid point until failure occurs. A formula into which the span, force and diameter of the bar are substituted yields the drying strength. See DSRN and DSTR tests for more info.
