Wedge-splitting tests for tensile strength and fracture toughness of concrete

This study presents a new approach for determination of tensile strength ft and fracture toughness KIC of concrete using wedge-splitting (WS) specimens as neither property can be easily measured because of the heterogeneous material structures. The Boundary Effect Model (BEM) was extended to WS geometry and relevant equations were derived so that more concrete properties can be determined by the load and displacement measurements. The new model...
