The additive can be either portland cement, lime or salt (sodium chloride). For stabilizing soils with cement, nearly all soil types can be used, from gravelly and sandy to fine-grained silts and clays. Generally, the more granular materials are used because they pulverize and mix readily and require the least amount of cement.
transfer to off-site effluent treatment plant. There is usually no process water discharge from cement or lime manufacture. Discharges to water result from the use of, mainly abstracted, cooling water or surface water (rain) run-off. Under normal conditions cooling water discharge would be the same quality as that abstracted or supplied.
