What the Romans Taught Us about Concrete

 · What the Romans taught us about concrete was mostly that you could build concrete structures without steel reinforcement that would last for two millennia. They also knew how to make concrete that could withstand the elements and that could even be used in underwater structures. Roman concrete production starting around 27 BCE rapidly went from a time when large blocks of concrete …

Pore fluids play an important role on the process of the deformation of rocks. Not only it affects the mechanical properties and the elastic velocities of the material, but it is also responsible in the generation of a whole kind of seismicity, characterized by lower frequency and longer tail (i.e. Long Period, LP, and Hybrid events) than the Volcano-Tectonic (VT) signals, generated by simple ...

The Dynamic Response of Etnean Sand and the Effect of Its ...

 · Quasi static and dynamic experiments were conducted to characterise the mechanical response of Etnean volcanic sand. Stress and strain histories were measured in near-uniaxial strain and near-uniaxial stress conditions at strain rates ranging between 5·10−4 and 1.5·103 s−1 using bespoke experimental setups. The effects of the lateral confinement and initial consolidation state were assessed.

Soil liquefaction

Soil liquefaction occurs when a saturated or partially saturated soil substantially loses strength and stiffness in response to an applied stress such as shaking during an earthquake or other sudden change in stress condition, in which material that is ordinarily a solid behaves like a liquid. In soil mechanics, the term "liquefied" was first used by Allen Hazen in reference to the 1918 ...
