Which I'm sure is related to Margaret. All these variations basically mean pearl in Greek. 'Peggy' was a vernacular term for a naval dockyard mess attendant and messenger who waited on the workers. I can't speak for the Royal Navy but for some reason it became translated to merchant ships.
SCCâs Cement Stabilized Sand is a clean and durable material made from a mixture of sand, cement and water that is used for backfill and bedding on a wide variety of civil projects. CSS is predominately used as backfill for retaining walls and storm sewer drainage.
Stabilization of foam is caused by van der Waals forces between the molecules in the foam, electrical double layers created by dipolar surfactants, and the Marangoni effect, which acts as a restoring force to the lamellae. The Marangoni effect is dependent on the liquid that is foaming usually not being pure.
