An experimental study of the influence of geometric scale on the ultimate strength of reinforced mortar beams failing in a flexural mode is presented. In the test were 132 beams, which included five different geometric scale ratios and two reinforcement ratios. Evidence of a significant relative increase in strength for the smaller specimens was found. Some potential causes for these increases are postulated and examined.
