Aug 01, 2019 Young's modulus values of EGY sample decreased significantly during heating, while FRA sample showed almost a constant value (about 80 GPa). The analyses showed that French basalt is more suitable for storage application than Egyptian basalt, because the latter had suffered from the formation of microcracks after thermal cycling due to its ...
tests indicated that the rock within each rock type was quite uni form. Results of the unconfined compressive strength tests on basalt y indicated, that as the loading rate was increased from 1 to 1.60 x 10 psi/sec, ultimate strength, total axial strain, and Young's modulus of elasticity increased. Total diametral strain decreased as load

It has been found that a rock core will split along a diameter when loaded on its side in a compression machine. This is the basis of the Brazilian test which is an indirect method of measuring tensile strength. A rock specimen having a disc shape with diameter (d) and thickness (t) …
The molten rock is then extruded through small nozzles to produce continuous filaments of basalt fiber. The fibers typically have a filament diameter of between 9 and 13 micron. They also have a high elastic modulus, resulting in excellent specific strength—three times that of steel.

Modulus of Subgrade Reaction - Which One Should be Used? By Wayne W. Walker, P.E. , F.ACI and Jerry A. Holland, P.E., F.ACI The modulus of subgrade reaction is an often misunderstood and misused concept for the thickness design of slabs-on-ground. Terzaghi in 1955 (Ref. 1, P. 300) attributed this confusion to the initial work by Hayashi in

modulus of the rock mass using empirical correlations with the rock properties. Heuze (1980) stated that the modulus of deformation of rock masses ranges between 20 and 60 % of the modulus measured on intact rock specimens in the laboratory. Hoek and Brown (1980a, b) proposed an empirical failure criterion for rock masses
Nov 04, 2020 Basalt was used as an ornamental stone in any historic and ancient cities in Jordan. Measuring the uniaxial compressive strength (UCS) and the tangent Young’s modulus (Et) in the laboratory requires premium quality specimens with special core dimensions. This research focuses on correlations both UCS and Et with Leeb Rebound Hardness Test (LRH).
elastic modulus using standard equations (Tutuncu et al,, 1994; Fig. 3), Dynamic moduli Ej for basalt and are approximately 30-60 GPa and -30GPa, respectively. The dynamic modulus of the basalt is about twice that of the underlying sedimentary rock. Compressional and shear wave velocities have also been measured underground at the Hanford site ...
Jun 09, 2015 Figure 9. (A) Static Young's Modulus plotted against the sample strength for all but the cyclically loaded samples. The results show that samples with higher Young's Modulus fail at higher stress, and typically deformation at a higher rate of 10 −1 s −1 results in a higher apparent Young's Modulus.
properties of volcanic rock remains largely unknown. Modelling of Mt. Etna has previously assumed values of Young’s modulus ranging from 50-100 GPa and a Poisson’s ratio of 0.25 [Cayol and Cornet, 1998; Bonaccorso and Davis, 1999]. • Here we report new results from stress-cycling deformation experiments on Etna basalt.
Jan 01, 2017 Young modulus is one of a basic geo-mechanical parameters used for the defining of the phenomena in rock mass. It is determined based on a uni-axial compressive test. According to the International Society of Rock Mechanics one may calculate it in three different ways as the tangent, secant and average modulus.

Apr 17, 2018 Basalt is an extrusive igneous rock derived from Lava and spread over different localities in Jordan. It can be used in industrial applications, and as construction materials. Before using basalt, it is essential to determine its dry density, porosity, uniaxial compressive strength, and Brazilian tensile strength. The testing procedure and sample preparation used to determine the engineering ...

Basalt is a type of igneous rock formed by the rapid cooling of lava at the surface of a planet. It is the most common rock in the Earth’s crust.[1] Basalt rock characteristics vary from the source of lava, cooling rate, and historical exposure to the elements. High quality fibers are made from basalt deposits with uniform chemical makeup.
Jul 07, 2014 Many models have been proposed to estimate the Young's modulus, E, of intact rock based on its uniaxial compressive strength, UCS. Deere's model, i.e., E = M R ⋅ UCS (where M R is the modulus ratio), is the most accepted one. However, traditional models cannot provide uncertainty estimates of parameters and predictions.
