ABSTRACT:
A method of introducing a casting compound composed of aggregates and a matrix with a hardening binder into a hollow space within a tubular sheathing of a tension member composed of one or more individual elements, particularly in the anchoring range of the tension member relative to a structural component. In accordance with the method, the aggregates are introduced first and the matrix is then introduced in the liquid state into the grain structure formed by the aggregates. A finely granular material is used as the aggregate. The finely granular material is introduced with the aid of compressed air through at least one tubular lance which is inserted in longitudinal direction of the tension member through the anchoring range.
