Triaxial test procedure The procedure followed in this test is mixing the cement and fibre contents of the samples calculated from the volume of dry sand by hand (ordinary method) until the distribution of fibres is achieved. Each sample is made up of five layers of mixed components, each weighing 125g. Then it is encased in a silicone membrane (38 mm diameter and 70 mm long). The layers are compacted slightly, then saturated, consolidated and sheared on triaxial. The test compression program (CD) has the following steps. 1- The preparation of the samples. 2- Applying a negative pressure to make the sample stable.
