    摘要： A composition of a solution of a metal salt of a dioic acid that provides corrosion resistance and moisture resistance is disclosed for application to post-construction materials. The composition may further include an effective amount of a thinning agent, e.g., isopropyl alcohol, ethanol, xylene or similar composition for application directly to the surface of the post-construction material. The composition is effective for reducing corrosion of post-construction materials, including unreinforced concrete or reinforced concrete, and reduces the permeation of moisture and/or the extension of cracks/fissures within the post-construction material. The composition may be applied to the post-construction material through brush applications, spray applications, mist applications or the like.

    摘要： The storage and processing times of sprayed concrete can be significantly extended by the addition of a retarder, a chemical compound which is capable of chelating with calcium ions. Preferred retarders are phosphonic acid derivatives which have at least one amino and/or hydroxyl group. The retarder can be used for both wet- and dry-sprayed concrete, the usual accelerators can be used for activation, and the strength is not adversely affected.

    摘要： Cast ceiling tile requires a particular rheology of its wet formulation for the dried tile to have a desired aesthetic appearance. The use of a latex binder rather than starch for cast ceiling tiles imparts the necessary rheological properties to the wet ceiling tile formulation. The tile is prepared by blending mineral wool with a premixture of water, latex, and filler, said premixture having a sharp yield point when measured with a recording Brookfield Viscometer. The latex is an alkali-swellable latex comprising (i) a C.sub.3 -C.sub.8 .alpha.,.beta.-ethylenically unsaturated carboxylic acid monomer in an amount from about 15 to about 60 weight percent based on the weight of the monomers in the cpolymers; (ii) at least one of a copolymerizable nonionic vinyl monomer in an amount from about 45 to about 30 weight percent based on the weight of the monomers in the copolymer and (iii) an additional late feed of nonionic vinyl monomer in an amount from about 10 to about 40 weight percent based on the weight of the monomers in the copolymer.
