A Direct Tensile Strength Testing Method for Concrete from Existing Structures

CivilEng, 2023
Tensile strength is a crucial property for the function, safety and durability of all concrete structures. The general procedure to assess the tensile properties of concrete from existing structures is to perform indirect tests and predict the tensile ...

Direct Tensile Test to Assess Healing in Asphalt

Transportation Research Record: Journal of the Transportation Research Board, 2016
Asphalt concrete has the advantageous ability to heal. During rest periods, damage present in the material is restored to a certain extent. Healing of the material can be observed in its regaining of strength and stiffness after rest periods. In this paper, a new test method is presented.

Methods and Points of Attention for the Direct Tension Test on Rock

Journal of MMIJ, 2016
Compared to uniaxial or triaxial compression tests on rocks, direct tension tests on rocks are not common in practice. As is well known, the reasons are because underground rock masses are usually under compressive stress state and/or because the direct ...

CURRENT COGNITION OF ROCK TENSILE STRENGTH TESTING BY BRAZILIAN TEST

Rudarsko-geološko-naftni Zbornik, 2015
Tensile strength in rock mechanics is a characteristic more frequently determined in the indirect rather than direct way. This paper presents a historical review of the development of the indirect method called the Brazilian test, comprising the period ...

A New Method for Direct Tensile Testing of Concrete

Journal of Testing and Evaluation, 2018
Abstract Different testing methods were used in previous studies to measure the direct tensile strength of concrete. However, these methods experienced several major deficiencies such as stress concentration at the end of the specimens because of inadequate gripping and loading eccentricity and nonuniform fracture plane because of ...
