Durability of Well Cements
Well cements are mixtures, whose binders are not yet standardized in Germany and Europe.
The mixtures contain additives, such as latex, that are not used in standardized binders. When in contact with soil and different types of geogenic water, the binders ensure the wells are not permeated.
Geogenic water can contain a high level of various ions and can cause an attack on the binder matrix.
The effects have not been extensively investigated thus far.
The working group examines the durability of these special cements.
