Direct tensile testing of Self-Compacting Concrete

Construction and Building Materials, 2016
Abstract This study explores a new procedure to determine the stress-strain behaviour of Self-Compacting Concrete (SCC) under direct uniaxial tension. Special steel claws were designed, built and installed at both ends of 100 × 100 × 500 mm SCC specimens. These claws were used to transfer the applied tensile forces to the specimens. The cross-section

Tensile behaviors of natural fiber and cement reinforced soil subjected to direct tensile test

Journal of Building Engineering, 2019
Abstract The present work was conducted to investigate the direct tensile behaviors including tensile strength, stress-strain curve, energy absorption, and crack patterns of soil reinforced by cement and natural fiber. In order to archive this, the direct tension test was designed to use for both reinforced and unreinforced specimens. The compacted 8-

Direct Tensile Testing of Concrete: A Review [PDF]

Concrete is strong in compression but weak in tension. The concrete tensile strength is important in reinforced concrete design since it impacts tension-related issues, such as crack development and the overall structural integrity. This paper summarises the challenges associated with the accurate measurement of concrete tensile strength.

Direct Tensile Tests on Concretelike Materials: Structural and Constitutive Behaviors

Journal of Engineering Mechanics, 2001
The complete stress-strain and stress-crack opening response of a concretelike material loaded in tension is examined starting from a series of displacement-controlled tests on notched cylinders, whose end sections were prevented from rotating (fixed platens). The test results refer to two very high-strength cementitious composites (tensile strength fc

A Direct Tensile Strength Testing Method for Unsaturated Geomaterials

Geotechnical Testing Journal, 2004
Abstract The current paper presents a new method for testing direct tensile strength of unsaturated geomaterials, guided by a method developed for concrete testing (Hannant et al. 1999). The developed equipment is used for measurement of direct tensile strength of unsaturated reactive basaltic clay soils and crushed rocks stabilized with

Determining Tensile Properties of Mass Concrete by Direct Tensile Test

ACI Materials Journal, 1989
Strength, strain capacity, and modulus of elasticity were determined for eighty large prism specimens with enlarged ends, 45 x 45 cm in cross section and 360 cm long, and eighty 10 x 10 x 55 cm small prism specimens. The relationships between the tensile properties of full-mix mass concrete with 150 mm maximum size aggregate (MSA) and that of the same ...

Seesaw apparatus for direct tensile testing of ring-shaped rock

2023
Background technology In the realm of rock mechanics, a crucial requirement is the availability of an experimental apparatus for conducting direct tensile tests on rocks. In current assessments of rock material properties, a multitude of analytical tests are performed using diverse material testing machines.

Direct tensile tests on prismatic concrete specimens

Cement and Concrete Research, 1981
Abstract A new type of clamping grips for direct tensile tests on concrete is presented. The grips make it possible to use prismatic specimens without inducing stress concentrations of too high a magnitude and this significantly simplifies the manufacturing of specimens and the performance of direct tensile tests.

Direct tensile tests on particulate agglomerates for the determination of tensile strength and interparticle bond forces

Advanced Powder Technology, 2017
Abstract The importance of direct tensile tests on solid and capillary bonded particulate agglomerates is investigated and compared to compression test measurements. The properties of wet agglomerates are varied by changing the contact angle by means of functionalization of the particle surface.
