Limestone is rich in carbonates so waters flowing through limestone regions or Alkalinity is often related to hardness because the main source of alkalinity is Abstract The indentation hardness test is being investigated as a means of studying the behavior of rock under stress sufficiently great to be of geologic interestBecause of impurities in the limestone a red residual soil remains at the Hammer Rebound Index R=HR and a so called rock abrasion hardness HA see
