additives in cement production

GCP Applied Technologies Inc., a leading global provider of construction products technologies, has launched two new cement additives, Opteva HE quality improvers and Tavero VM grinding aids, to deliver higher performing, lower cost cement production.

Concrete production is the process of mixing together the various ingredients—water, aggregate, cement, and any additives—to produce concrete. Concrete production is timesensitive. Once the ingredients are mixed, workers must put the concrete in place before it hardens.

For example, Class H cement with the proper additives has routinely been used at depths up to 20,000 ft. In addition to the cement, other factors, such as the correct Bottom Hole Circulating Temperature (BHCT), should be considered when designing a cement slurry to meet well requirements.

The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches. Secondary crushers or hammer mills then reduce them to .

Effect of Grinding Aids on Wet Grinding. A variety of additives have been shown to have grinding aid characteristics for grinding cement clinker. Typical among these are amines, organosilicones, glycols, resins, cod oil, kojic acid, carbon blacks, wool grease, calcium sulfate, urea, asphaltenes, etc.

Polytrol® FL 32 is a dispersing fluid loss additive. Excellent filtration control and flow properties in oilwell cement slurries up to 200 ºF. Permits the design of lowviscosity slurries. A very mild retarder, even at temperatures as low as 100 ºF. Specifically suited for shallow well cementing.

Depending on the type of cement, granulated blast furnace slag, limestone, etc. may additionally be used in cement production. Ground cement is stored in cement silos, from where it is loaded into railway cars or tank trucks, or packed into paper bags.
