A SINGLE- OR MULTIPLE COMPONENT COMPOSITION FOR PRODUCING A HYDROGEL
The invention is directed to a single- or multiple-component composition, which forms upon mixing with water a (meth)acrylic hydrogel and which composition comprises at least one water soluble at room temperature liquid (meth)acrylic compound supported on a solid carrier and/or an aqueous solution of at least one at room temperature solid or liquid (meth)acrylic compound, a free-radical initiator, and optionally a catalyst for the initiator. The invention is also directed to a method for producing a hydrogel, to a hydrogel, to an acrylic injection material and to a method for sealing cracks, voids, flaws and cavities in building structures.
A sealer composition for a cementitious substrate, a cementitious structure sealed with the sealer composition, and a method of sealing a steel reinforced cementitious structure with the sealer composition. The sealer composition includes a substantially non¬ aqueous blend of a first silane, a second silane having a higher molecular weight than the first silane, and a corrosion inhibitor. The corrosion inhibitor is soluble in silane, soluble in solvent-diluted silane, and at least partially soluble in water. The cementitious structure includes a cementitious substrate and the sealer applied to the surface of the substrate and at least partially penetrating into the substrate. The method of sealing a steel reinforced cementitious structure from intrusion of corrosion-causing agents includes applying the sealer to the surface of a steel reinforced cementitious substrate and permitting the sealer composition to penetrate into the substrate to seal the substrate.
A mixer (1) has a drum (2) with at least one inlet (6) and one outlet (7). The mixer (1) further has a drive (3) and a stirring shaft (4), which is arranged in the drum (2) and coupled to the drive (3). The mixer (1) further has a conveyor device (5) which is arranged in the drum (2), on the same axis as the stirring shaft (4).
