Hoek Cell for Triaxial Test (Hoek-Cell)
The Hoek Cell is a simple and inexpensive triaxial cell that tests triaxial strengths of rock or concrete core specimens up to a pressure of 70 MPa. They are designed to accept samples of X, AX, 1.5 in, BX, NX and NX sizes and offer a fast and effective way of dealing with samples with accessories for permeability testing.
The Hoek cell is made of a hollow steel cylinder with two removable end caps. The cylinder can withstand internal hydraulic pressure of up to 70 MPa.
Two hardened and ground spherical steel seats apply an axial load to the flattened ends of the sample. In addition, a ‘jacket’ with the same diameter of the sample and a rubber sealing sleeve works to separate the specimen from the cell fluid.
