Grout

When grout is called the mortar , which for pressing the cladding tubes in which the tension wires or strands in prestressed concrete will have been laid, used.

Components

Grouts are generally made up of high quality Portland cement and water. In addition, small amounts of additives such as Daragrout (formerly Tricosal) are available as a grouting aid in order to achieve optimal flowability and adequate security against too early solidification. The tendons, which are subject to high tensile stresses, are sensitive to corrosion and must be completely enclosed by the grout.
