Investigation of the Behavior of Concrete under Tensile Strain Gradients

摘要

The results of an investigation into the relationship between several standard tests on concrete are reported. Specifically, the modulus of rupture test, the split cylinder test and the cylinder compression test are compared with a direct tension test of a 3.5 inch rectangular specimen subjected to a tensile strain gradient. The primary experiment involved mortar specimens, although concretes containing limestone and 'solite,' a lightweight aggregate, were also investigated. (BPR Abstract)
