New Product Announcement:

The new Static Segregation Column, model HM-597 from Gilson features a unique and innovative design that allows a single person to perform the static segregation resistance of fresh self-consolidating concrete (SCC) mixes. The rugged frame and moving parts of the newly redesigned Static Segregation Column are fabricated from 1in (25mm) thick high-density polyethylene plastic and the column mold is constructed of schedule 40 PVC, providing fast and easy cleanup and corrosion-free durability.

After the full-height main column of the HM-597 is filled with concrete, struck off, and allowed to settle, the top tier is pushed aside to deposit the top sample into the collection vessel. The middle tier is then moved over to discard the middle section of the sample, leaving the bottom sample in the lower tier of the column, ready for retrieval and testing.

Concrete from the top and bottom sections is easily recovered and washed over a 4.75mm (No. 4) sieve. The mass of the coarse aggregate for the top and bottom sample sections can then be compared to determine the percent of static segregation.
