Abstract (en)

[origin: EP1547985A1] The hydraulic bonding agent for adding to a dry material, e.g. water for Portland cement, is in a dry condition as a liquid additive (1) within a micro-pore carrier (2), with a pore diameter of 3-10Å and preferably 4-8Å, to migrate into the dry cement in the required formulation for the composition (3) to be bonded together. The additive can also be used to prepare a mortar for the repair of concrete. The liquid contents can also contain an anti-corrosion agent to protect the concrete reinforcement rods (4).
