Estimating the strength of rock materials - SAIMM

African mining industry during the last twenty years, simple and easy-to-use methods for the estimation of the uniaxial and triaxial strength of rock materials are needed. It is shown that the uniaxial compressive strength of rock can be conveniently determined from the point-load strength index, which isobtained underground.

GEOPOLYMERIZATION OF COPPER MINE TAILINGS By Fenghua .

curing temperature to 150℃ caused a decline in compressive strength. The maximum strength value obtained by them was about 80 MPa. In 2011, Saeed et al [17], conducted the geopolymerization based on copper mine tailings. In his papers, he studied the factors including Si/Al ratio, alkali concentration (10-15M), curing.

Ultimate tensile strength - Wikipedia

Ultimate tensile strength (UTS), often shortened to tensile strength (TS), ultimate strength, or Ftu within equations, is the capacity of a material or structure to withstand loads tending to elongate, as opposed to compressive strength, which withstands loads tending to reduce size. In other words, tensile strength resists tension.
