    摘要: A composition for hardening concrete that has a pH of less than 10, and may have a pH of 8 or less. Thus, the hardening composition may be free of or substantially free of alkaline materials. The hardening composition is water-based and includes silica particles and stabilizer, which may be present on portions of the surfaces of the silica particles. The stabilizer may be aluminum-based (e.g., it may comprise alumina, etc.). In use, the hardening composition is applied to the surface of concrete, either alone, with curing compounds, or as part of a polishing process. Any residue that remains on the treated surface may simply be swept, blown, or sprayed away.

    摘要: A method of resisting corrosion in concrete containing metal elements is provided. It includes introducing into fresh concrete, containing metal elements, at least one compound capable of sequestering chloride ions. The method may also involve employing a compound which is capable of establishing a corrosion resistant oxide layer on the metal reinforcing elements. The invention also includes certain compounds which may be employed in the method as well as concrete structures containing the compounds. In another embodiment of the invention, concrete structures may be rehabilitated by providing an overlay containing a compound of the type which will contribute to corrosion resistance either through chloride ion sequestering or creating barriers around metal structural elements with the overlay being provided in situ or as a preformed member and with possible use of a slurry in combination with an overlay segment.

    摘要: A mechanically activated pozzolan prepared from granitic quarry fines. Quarry fines are milled by a high-energy milling process to convert the essentially inert raw granitic fines into a chemically reactive state. When added to a portland cement mortar mixture, mechanically activated fines combined with calcium hydroxide to improve the strength of the cured mortar compared to a similar mixture prepared with raw fines. Mortars prepared with mechanically activated granitic fines typically show strength values comparable to or exceeding similar mortars made using fly ash as a pozzolan. In some instances, the strength of a mortar prepared with mechanically activated granitic quarry fines exceeded a mortar prepared using 100% portland cement as the cementitious component.
