Definitions
- the invention relates to an agent for the protection of structural materials, in particular concrete and brick, against water.
- the agent according to the invention fulfills the above requirements.
- the agent according to the invention is characterized in that it contains, as the active component, with the cation present in the structural material, advantageously calcium ion, a water-soluble compound containing a non-water-soluble precipitate.
- the basis of the invention is the recognition that in the case when such a water-soluble anion reacts with the calcium ion present in the concrete that forms with the insoluble precipitate, this precipitate becomes the capillary of the
- the presence of such an anion is necessary which forms a water-soluble salt with a corresponding cation, from which an insoluble precipitate forms in the structural material by cation exchange.
- the polycarboxylic acids optionally substituted by hydroxyl groups containing 2-8 carbon atoms and also optionally containing double bonds contain such anions.
- the organic dicarboxylic acids optionally substituted by hydroxyl groups are also worth mentioning.
- Such acids are e.g. B. malic acid, citric acid and fumaric acid.
- An advantageous anion is e.g. B. Oxalate, but above all the tartaration.
- the agent contains tartaric acid and sodium carbonate, which ver bindings can be reached easily and cheaply. These compounds form sodium tartar in an aqueous medium, which penetrates into the capillary with the calcium oxide, calcium carbonate, etc. reacts to insoluble calcium tartar.
- the agent can serve as a cation source compound or. Cation any compound or cation are used which forms water-soluble compound with the anion used. An alkali metal ion or alkali metal compound whose salts are generally water-soluble is expediently used.
- tartaric acid sodium carbonate or - if the active ingredient is a compound - sodium tartarate or tartar / potassium hydrogen tartar / are suitably used.
- the agent according to the invention contains at most one additive known per se in construction practice.
- the agent expediently contains cement and sand, while in the case of protecting bricks against water cement and bentonite, and, if appropriate, sand.
- the agent expediently contains cement and sand, while in the case of protecting bricks against water cement and bentonite, and, if appropriate, sand.
- others that are equivalent to the above or suitable for the same purposes can also be used
- the agent according to the invention is used in such a way that the agent is applied to the prepared concrete surface in any manner known per se, such as e.g. B. is applied by brushing, spraying, etc.
- the surface should be moistened before application to allow the possibility of diffusion into the pores.
- the wall In the case of treating a brick wall, the wall should be cleaned of any mortar and other dirt that may still be present, after which the treatment should be carried out as above.
- Moisture should be protected one can proceed with a technology which is known per se, by making holes in the brick wall along a horizontal line, possibly at the same distance from one another, expediently in a width of 10-15 cm, and that according to the invention Medium is filled into the holes with a suitable device, but also with a funnel.
- a suitable device possibly at the same distance from one another, expediently in a width of 10-15 cm
- the wall will not suffer any strength or other damage.
- an advantage of the agent according to the invention is that the air permeability of the treated object does not change.
- composition of the agent according to the invention can, for. B. be the following:
- the agent according to Example 2 can also be prepared by using water glass in the same instead of sodium carbonate
