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.
The most common form of stabilized soil is soil cement, a mixture of existing soil and 5 to 16 percent Portland cement. No aggregate or sand is used, so costs are less than those of concrete or asphalt are. The surface looks like local soil, but is hard with a compressive strength up to 1500 pounds per square inch.
