2015-4-24 Equation 1 has been shown to closely approximate the prism strengths predicted by the elastoplastic finite element program for block compressive strengths ranging from 4 to 40 MPa and for mortar strengths ranging from 2 to 20 MPa. However, a more direct examination is to compare the calculated prism strengths from Equation 1 to the measured prism strengths reported in the literature.
