Gilson Slump Cones measure the workability of a fresh concrete mix in accordance with applicable ASTM and AASHTO standards. The slump cone test is performed for acceptance purposes, to record mixture characteristics, or as an indirect method of determining the water/cement ratio.
The cones are constructed of rust-resistant spun steel or high-density plastic. The cones meet inch (4x8x12) or metric (100x200x300) dimensional requirements for holding the compacted concrete layers.
The slump cone test can be carried out in the lab or field. Slump base plates are available and can be used interchangeably with steel or plastic cones.
