DetailsThe average compressive strength and standard deviation were found to be 15,707 psi and 398 psi, respectively. Analysis of the data proves that the compressive strength of marble is not influenced by steel end platen size or thickness. Similarly, low standard deviation and lack of trend occurred for the other three rock types.
