As illustrated in Fig. 10, adding basalt fiber to the matrix asphalt increased the three moduli, with an increase of 7.9% in elastic modulus, 1.3% in bulk modulus, and 6.1% in shear modulus. This indicates that the micro-mechanical properties of basalt fiber-reinforced asphalt are enhanced, but the increase is not obvious.
However, the alamosite bulk modulus is close to some silicate materials such as natural tholeiite basalt glass, ~52 GPa [30], nepheline (NaAlSiO 4 ), ~45 GPa, and slightly larger than sodium ...
Calculate Bulk Modulus from Youngs Modulus and Poisson's Ratio; Typical Values of Some Materials; See Also; Summary. The bulk modulus measures a substance's elastic resistance to change in volume when under uniform loading in all directions. It can be thought of as an extension of the Youngs Modulus into three dimensions. The formula for ...

The isothermal bulk modulus K T and the pressure derivative of the bulk modulus K′ of the melt differ from the values obtained by Circone and Agee (1996): K T = 15.5 GPa and K′ = 5.2 at 2173 K. This result indicates that the high-Ti basalt melt is more compressible than previously reported.

The amount of change results from the frequency dependent velocity when basalt cores are saturated with water. Larger elastic changes due to fluid substitution are measured for the bulk modulus, with an average change of 30%. The water and CO2 saturated rock bulk modulus is modeled with two rock physics theories.
By using the in situ permeability data of a basalt rock mass with shears, the change in permeability of the shear is estimated, which has been utilized to calculate the porosity and bulk modulus at different depths. The results clearly show that the porosity decreases with depth while the bulk modulus increases with depth.

This case uses a dry bulk modulus calculated with the mineral modulus of 40 GPa, D = 2, and a water modulus of 2.8 GPa. The water saturation effect was calculated for three mineral moduli of 65, 40, and 32 GPa. Results show that for the same K d and K f, bulk modulus increment ΔK because of fluid saturation increases with increasing mineral ...
However, when samples are water saturated, the bulk modulus of the rock is frequency dependent. Modeling with Gassmann's equations predicts the measured saturated rock bulk modulus for all fluids for frequencies below 20 Hz but underpredicts the water-saturated basalt bulk modulus for frequencies greater than 20 Hz.

First of all, (kg/cm^2)*10^5 is not the correct unit for Young's modulus, which should be in units of pressure. Pressure is a force over an area, so N*m^-2 or in SI units kg*m^-1*s^-2. Maybe what you were going for was gigapascals, which would be (N/cm^2)*10^5, although a better way to write that would just be (N/m^2)*10^9.

1 INTRODUCTION. Storage of carbon dioxide (CO 2) in volcanic rocks, such as basalt, peridotite and tuffaceous rocks, rich in reactive and divalent cations, is a valid approach for reducing the amount of greenhouse gases in the atmosphere (e.g. Lackner et al. 1995; Takaya et al. 2015; Wu et al. 2021)..
