In this paper, we propose an innovative method for conventional triaxial tests of concrete with a confining cell.

The polyvinyl chloride (PVC) pipe is used as a mould to cast concrete and also as a membrane to isolate the concrete specimen from oil under confinements.

This method is termed as PMM (i.e., PVC pipe is used as a mould and membrane).

However, a heat-shrink sleeve is used as a membrane in the traditional test method (TMM).

Specimens were made from mortar without coarse aggregates in the present experiment.

Under six confinements (0–70 MPa), the conventional triaxial compression tests were performed on ultrahigh-strength (150 MPa) and high-strength (82 MPa) mortar specimens by PMM and TMM.

The results indicate the following: (i) there is a characteristic confinement p0; when the confinement is lower than p0, the strength by PMM is higher than that by TMM; on the contrary, when the confinement is higher than p0, the strengths by both methods are almost identical.

In this work, p0 is between 0 and 5 MPa.

(ii) When the confinement is 5–70 MPa, the relationship between the peak stress of high-strength mortar and confinement is characterized by a monotonically rising straight line; however, a monotonically rising upward convex curve describes the peak stress of ultrahigh-strength mortar related to the confinement.

(iii) The residual strength using PMM is significantly higher than that using TMM at zero confinement or lower confinements, but the residual strengths by these two methods are approximately identical at higher confinements.

(iv) The transverse cracks appear in the mortar specimen inside the PVC pipe after enduring a triaxial loading using PMM.

However, there is no such phenomenon when TMM is applied.
