Concrete Pour over Rebar (reinforcing steel, reinforcement steel)... Liquefaction is a physical process that takes place during some earthquakes that may lead to ground failure. As a consequence of liquefaction, soft, young, water-saturated, well sorted, fine grain sands and silts behave as viscous fluids rather than solids. Artificial earthquakes are utilized during the pouring of cement to smooth and flatten!
