Uniaxial compressive rock strength determination

Uniaxial compressive rock strength determination Rebound hardness is perhaps the most frequently method used in rock testing to determine uniax-ial compressive strength (UCS). Proceq's RockSchmidt provides not only the possibility of obtain-ing the UCS, but also of sending the complete register data and report direct to the computer.

Rock Failure Topics

1. When rock fails in compression, the compressive stress exceeds the compressive strength. 2. Even poorly-consolidated sands are characterized by a high coefficient of internal friction. Weak rocks are weak because they lack cohesion. 3. Intermediate principal stress (S 2) probably influences compressive strength only at very great depth. 4.
