Estimating the direct tensile strength of rocks from indirect tests
Arabian Journal of Geosciences, 2021Within the scope of this study, a series of experimental, numerical and statistical analyses were performed in order to find the coefficients that would allow the accurate determination of the tensile strength values of the rocks. In this context, direct and indirect tensile strength values of 9 different rock types including sedimentary, metamorphic ...

A Direct Tensile Strength Testing Method for Unsaturated Geomaterials
Geotechnical Testing Journal, 2004Abstract 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

Comparative Study on the Bond Strength between Direct Tensile Test and Indirect Tensile Test for Bonded Concrete Overlay [PDF]
Journal of the Korean Society of Civil Engineers, 2013 Bonded concrete overlay is a favorable maintenance method since the material properties are similar to existing concrete pavements. In addition, bonded concrete overlay has advantage of structural performance based on being bonded together, both for the overlay layer and the existing pavement which perform as one monolithic layer.

Tensile Strength and Fracture Surface Morphology of Granite Under Confined Direct Tension Test
Rock Mechanics and Rock Engineering, 2021The tensile strength of rock is a crucial parameter for the stability assessment and reinforcement design of rock engineering, which is commonly determined by indirect tension test or uniaxial direct tension test. However, the rock in slopes and underground caverns is often in a direct tension stress state under confining pressure, due to the stress ...

New proposed direct tensile strength test for concrete
2014The evaluation of the tensile strength and determination of the tensile stress-strain curve using indirect tests becomes approximate hence there is a necessity for exploring direct tensile strength measurement. This investigation is part of ongoing research on the development of direct tensile strength measurement. In this paper direct tensile strength
