Cementitious Grout Infilling Of Deep Brine-Filled Salt
This paper presents a case history of the stabilisation by grouting of four 5-m high brine-filled salt mines located at approximately 90 m depth in the Cheshire Basin in the United Kingdom. The stabilisation works involved pumping 800 000m3 of a cement brine and Pulverised Fuel Ash (PFA) grout mix into the mines.

USAMethods for producing aerated cementitious
An aerated cementitious composition is produced by feeding a mixture comprising cement and foaming agent to a mixing chamber open to atmosphere together with a feed of liquid. The ingredients are mixed and the wetted mixture pumped to a desired site the capacity of pumping being greater than the feed rate of the ingredients into the mixing chamber such that air is drawn into the mixing chamber.

Compatibility Of Grouts With Hazardous Wastes
Typically cement grout cannot be used in fine grained soils with voids less than 0.1 mm wide because the large cement particles plug the soil matrix and prevent grout penetration (Bowen 1981). Cement grout may be applied to fractured rock that has voids of sufficient size to ensure penetration of the grout.
