A multi-component inorganic capsule anchoring system can be used for chemical fastening of anchors, bolts, screw anchors, screw bolts, and post-installed reinforcing bars in mineral substrates. The multi-component inorganic capsule anchoring system contains a curable powdery ground-granulated blast-furnace slag-based component A, and an initiator component B in aqueous-phase for initiating the curing process. The powdery ground-granulated blast-furnace slag-based component A contains further silica dust. The component B contains an alkali- or alkaline earth-hydroxide, alkali- or alkaline earth-carbonate, or alkali-or alkaline earth-sulfate component.

Hexavalent chromium-free slurries are provided that are capable of achieving a full cure at temperatures as low as 330-450 degrees F., thus making the coatings especially suitable for application on temperature sensitive base materials. The slurries are suitable in the production of protective coating systems formed by novel silicate-based basecoats that are sealed with novel phosphate-based topcoats. The coating systems exhibit acceptable corrosion and heat resistance and are capable of replacing traditional chromate-containing coating systems.

The present invention refers to a base formulation which serves to form a final product intended for the repair, maintenance or rehabilitation of concrete structures. Primarily, the base formulation contains cement in a percentage of 35% to 45% by weight of the final product. The base formulation also possesses amorphous glass in a proportion of 20% to 30% by weight of the final product, in ground from common glass, recycled glass or soda-lime glass. Finally, the base formulation may further possess solid quartz microspheres in a proportion of 10% to 20% by weight of the final product. This provides the final product with many desirable properties, such as high mechanical strength; high chemical resistance; easier application; easier ability to polish; prevents cold seals, leaving the final product thermally and dimensionally stable, among other desirable properties. The final products may include concrete correctors, waterproofing agents, coatings, among others.
