摘要

As it is well known, indirect methods such as splitting (Brazilian)tensile test or 3–4 point bending tests are often preferred to directtensile test for determining tensile strength of concrete. Zi et al. [1] has proposed a biaxial flexure test method to measure the tensile strength of concrete indirectly. In this discussion, the similarities anddissimilarities of the proposed method with the well known biaxialflexure test method [2,3] will be compared. A biaxial flexure testmethod has already been used for ceramics and also some cementbased materials like macro defect free (MDF) cements starting fromthe 1960s and even this method was standardized by ASTM [3] in1978 (however, it was withdrawn in 2001). Therefore, I would like tocontribute their study while giving a short history of biaxial flexuretesting since the writers did not mention anything about these earlierefforts and I also would like to discuss some points in their article.
