Abstract
Mineral forming solutions can be prepared by using of special precipitation inhibitors. These are compounds allowing the mixing of solutions which are incompatible under normal conditions, for example BaCl2 and Na2SO4 solutions or lime suspensions and diluted sulfuric acid. Clear, temporary stable solutions are obtained. If these are used as grout, directed precipitation takes place in the flow paths. The paper summarizes the fundamentals of the technology and gives an overview about the characteristics of gypsum and BaSO4 forming solutions. Their immobilization effect was proven by column tests, which are discussed in detail.
