Triaxial and Uniaxial Tests | Mining | SGS

The unconsolidated, undrained compressive strength of the soil is the maximum deviator stress obtained during the test under the selected confining pressure. This test method is also useful for determining total stress (undrained) strength properties such as apparent cohesion and the stress/strain relationship of the soil.

Effectiveness of a densification process to create strong and durable bonding in densified products such as pellets, briquettes, and cubes can be determined by testing the strength (i.e., compressive resistance, impact resistance, and water resistance), and durability (i.e., abrasion resistance) of the densified products.

Compressive Strength - an overview | ScienceDirect Topics

Compressive strength is the standard strength parameter of concrete that can be evaluated under site conditions as well. The most common method is to use cylinder cores drilled off the structure. Momber (1998b) was probably the first to suggest to use the way how a cylinder fails during the compression test as a criterion of the material behaviour during hydrodemolition.

Properties of Biobased Rigid Polyurethane Foams Reinforced ...

The effect of incorporating 1–7% microsphere and nanoclay fillers on the physical properties of polyurethane (PU) foams containing 15% soybean oil-based polyol was investigated. Increasing filler percentage reduced the PU foam density. The compressive strength of PU foams decreased slightly when increasing the microsphere content from 1 to 3% and then increased.

The normalized compressive strength of benchmark foam (B1) is 940.0 kPa, while the values for HF1 (70:30), HF2 (60:40) and HF3 (50:50) foams are 765.4, 677.3 and 632.9 kPa, respectively. The compressive strengths of the rigid PU foams decreased with increasing amount of transesterified palm olein-based polyol in the formulation.
