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.
Typical design examples of some of the externally stabilized and. internally stabilized walls, i.e. design of reinforced concrete cantilever retaining walls, metal. strip reinforced walls, geotextile reinforced walls and anchored earth walls of different heights. have been provided for the purpose of cost comparison. The analyses reveal that the internally. stabilized walls are significantly more economical compared to the externally stabilized wall. considered in this study, and this economic benefit increases with increasing height of the walls.
