The penetration apparatus provides a rapid assessment of static segregation resistance of self-consolidating concrete. While it does not actually measure static segregation, it does provide a quick assessment of whether static segregation is likely to occur. The included scale is marked in 1mm increments and is replaceable. Test apparatus is used in conjunction with an inverted standard slump cone, order H-3640 for this purpose. You may also need a strike-off bar, order H-2785.34.
