The dynamic modulus of crushed gravel concrete shows a decay of 20 % in the course of exposure but recovers later again. This result means that the dynamic modulus of elasticity is not very sensitive to the alkali reaction and is therefore not a good indicator for ASR.

RELATIONSHIP BETWEEN COMPRESSIVE STRENGTH AND MODULUS OF ELASTICITY OF HIGH-STRENGTH CONCRETE ... modulus of elasticity, E, is expressed as a function of compressive strength a and unit weight, ... use of a wide variety of crushed stone has revealed that the difference in unit weight is not the only factor to account for the

news

In samples with a grain size of 4.1 nm, the elastic modulus was lower (178 GPa). In NC titanium, the volumetric share of grain boundaries is an order of magnitude lower than that in Ni–P, where the decrease in the Young's modulus is substantial. Hence this may be not the only factor which influence on the elastic modulus value.

Hence, the modulus of subgrade reaction, which is the function of soil settlement and the external pressure,is used for flexible foundation design. Correlations. The most common – and probably the safest – answer to the question of correlation between bearing capacity and the modulus of subgrade reaction is that there is no correlation.

The Young's Modulus (or Modulus of Elasticity) describes the limit for small strains of the rate of change of stress with strain a material is able to support. Many natural stones have a Modulus of Elasticity of around 50 Gpa (which translates to 50.000 N mm -2, depending on the stone), with pure Quartz reaching a Young's Modulus of 71.7 GPa.
