A novel experimental method for measuring the direct tensile strength of concrete

This study deals with the development of a load-converting device designed for measuring the direct tensile strength of the concrete. In this regard, a new testing technique based on a novel testing device and modified cylindrical (& Oslash;100 x 200) molds for the preparation of concrete sample...

A novel experimental method for measuring the direct tensile strength of concrete
description This study deals with the development of a load-converting device designed for measuring the direct tensile strength of the concrete. In this regard, a new testing technique based on a novel testing device and modified cylindrical (& Oslash;100 x 200) molds for the preparation of concrete samples is explained. The embedded rod method was adopted to transmit the uniaxial tensile load to the specimens using the universal compression machine and the current converting device. In order to examine the reliability of the suggested test method, a comparison with indirect tensile methods (splitting and three-point loading flexural tests) was made.
