Abstract
An understanding of the tensile capacity of plain and fiber-reinforced concrete is needed for design. Typical designs use correlations based on the flexural capacity of a prismatic beam. Because of anisotropy, however, determining tensile capacity from correlations is more uncertain in additive manufacturing. Therefore, a simple and reliable method for measuring the direct tension of concrete is needed. This paper describes and evaluates a direct tension test of fiber-reinforced concrete that is being developed in ASTM Subcommittee C09.42 on Fiber-Reinforced Concrete. Alternate specimen geometries are discussed, and select results from 100 tests are evaluated statistically. Modifications to the method for use in additive manufacturing are proposed and qualitatively described.
