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 method of stabilization is chosen based upon evaluation of the type of hazard involved, magnitude of the problem, potential triggering mechanisms, threat to life and cost. The primary focus of this paper is on the various engineering techniques to stabilize a site with minimal landform alteration. This discussion is not intended to replace professional site inspections or designs by engineering geologists and civil engineers.
