Interpretation formulas for in situ characterization of mortar strength

Mortar Strength, A Problem of Practical Statistics.

Mechanical characterization of mortar beams

The mechanical characterization of mortars is problematic due to their sensitivity to stress concentration defects, namely pores and flaws. In this paper, data on three-point bending, Young’s modulus and fracture toughness of mortar beams are presented and discussed. Here, Weibull statistics is applied to analyse flexural strength of the developed mortar. Based on data obtained according to the...
