<p>The invention relates to a method for stabilizing the binder-gel formation time during the consolidation of a geological formation in the presence of one or more catalytically active substances, in which a binder is infiltrated into the formation, optionally a part of the infiltrated binder is again expelled by rinsing with a gas or a liquid and the binder remaining in the formation is cured, wherein the binder comprises a mixture of A) a heterocondensate that can be obtained by hydrolysis and condensation of at least one hydrolyzable silicon compound and at least a metal, phosphorus or boron compound, the metal being selected from Al, Ge, Sn, Pb, Ti, Mg, Li, V, Nb, Ta, Zr and Hf, B) at least one organic polymerizable monomer or oligomer, which has one C-C double bond, and C) at least one thermal polymerization initiator without peroxide function. The gel formation time of the binder can be stabilized by using a peroxide-free initiator so that the setting behavior of the binder is relatively independent of changes in the type and concentration of additives in the binder, pH changes and catalytically active substances in the respective geological formations or in the production equipment.</p> |
