In very high-strength concrete mixtures (greater than 70 MPa) the crushing strength of the aggregate can be a limiting factor to the ultimate compressive strength In lean concretes (with a high water-cement ratio) the crushing strength of the aggregates is not so significant

As per test results it may be concluded, that grinding fineness improving results in concrete ultimate compressive strength increasing (Fig 5), and, at the same time, density increasing, see Fig 6 Fig 6 Effect of dolomite limestone fine powder (specific surface 5500cm 2 ,

Compressive Strength of rock: The RMR value depends up on the unconfined compressive strength (q u ) of the rock and it can be determined from laboratory compression test on a prepared rock specimen Or otherwise find out the approximate value of compression strength from point load test on intact pieces of drill core

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

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
