Investigating the effects of loading rate and mixing design on concrete's direct tensile strength using the CTLC test [PDF]
Analytical and Numerical Methods in Mining EngineeringTensile strength of concrete is measured using direct tensile tests on rectangular concrete samples with dimensions: 19 cm in length, 16 cm in width, 6 cm in thickness, and a central hole of 9 cm in diameter.

Mechanical Characterization of Cemented Paste Backfill
Eng, 2023 Mechanical characterization is important to the design and analysis of cemented paste backfill (CPB) structures. Unconfined compressive strength (UCS) tests have been widely used owing to their relative simplicity to characterize a material’s response to

Laboratory Tensile Strength Testing of Clay Soils using Direct Measurement
Japanese Geotechnical Society Special Publication, 2019 Clay has wide application in engineered barriers, such as buffer barriers in deep geological nuclear waste disposal, clay liners in landfill, and earthen slopes and embankments, to name a few. However, most clay soils have a high potential to crack under extreme weather induced moisture loss. From a macro-mechanical view, clay tensile strength which is

A COMPARISON OF TESTING METHODS FOR DETERMINATION OF SPRAYED CONCRETE TENSILE STRENGTH
Acta Polytechnica CTU Proceedings, 2019 Sprayed concrete is important construction material in tunnelling. Primary lining is essential in NATM where the sprayed concrete can be loaded by tension due to bending moments.

Interfacial Bond Properties between Normal Strength Concrete and Epoxy Resin Concrete
Advances in Materials Science and Engineering, 2021 It is necessary to pay attention to the bonding strength of the interface between precast normal strength concrete (NSC) and cast-in-place epoxy resin concrete (EMR) when using EMR as a repair or filling material or an overlay in bridges’ rehabilitation.

Effect of Fibers on the Mechanical Properties and Mechanism of Cast-In-Situ Foamed Concrete
Advances in Materials Science and Engineering, 2022 The cast-in-situ foamed concrete is inherently susceptible to cracks due to its brittleness under external loads. In order to improve its mechanical properties, this paper investigated the effect of fibers on the mechanical properties and mechanism of ...

A Direct Measurement Method for the Uniaxial Tensile Strength of Rock
BuildingsA universally applicable direct tension test method is proposed in this paper based on the concept of “compression-to-tension”. Using this method, one or two typical rocks were selected for each of the three types of rocks.
