Hoek Cells

Hoek cells are used to measure the strength of cylindrical rock specimens, which are subjected to triaxial compression. They are comprised of a steel body and two steel end caps, which are screwed to the body of the cell when in use. The body has two, self-sealing couplings; one of them is for connecting to the hydraulic pressure system, the other is for de-airing the cell chamber and the attachment of a pressure measurement device. Four sizes are available.
The Hoek cell consists of the following: cell body complete with two screwed end caps and two self-sealing couplings, two spherical seats and pistons, hardened and ground, one specimen jacket.
