Estimating the term…
A mortar composition, curable by frontal polymerization after heat initiation, is described, wherein are contained a) at least one polymerizable monomer and/or at least one curable resin, b) at least one polymerization initiator, which can be activated and/or released thermally at a temperature above 30° C., for the polymerizable monomers and/or curing accelerator for the curable resin and c) optionally at least one filler, the nature and amount of polymerizable monomer or curable resin and polymerization initiator or curing accelerator being selected so that a polymerization front velocity of at least 10 cm/min results after the polymerization is initiated, as well as a method for fastening tie bars, reinforcing steel or the like in solid substrates.
A mortar composition, curable by frontal polymerization after heat initiation, wherein are contained
A method for fastening tie bars, reinforcing steel or the like in solid substrates, wherein the mortar composition of at least one of the preceding claims is brought into the dowel hole, the tie bar, the reinforcing steel or the like is introduced and the frontal polymerization initiated by heating the surface layer of the mortar composition to a temperature above the reaction temperature of the polymerization initiator, polymerization accelerator and/or curing agent.
