    摘要: Exemplary compositions and methods for reducing hexavalent chromium in cementitious compositions involve the use of a liquid additive composition, comprising stannous chloride. Along with the stannous chloride may be used at least one co-additive comprising an antioxidant, oxygen scavenger, or mixture thereof, and/or at least one agent comprising a cement grinding aid, cement quality improver, or mixture thereof.

    摘要: The installation system and method for installing an architectural covering material to a substrate surface utilizes an adhesive mat having layers of adhesive and release layers arranged to allow the covering material to be initially positioned, and later repositioned to be permanently set. The adhesive mat includes a planar carrier member, one or more adhesive layers on at least one planar side of the planar carrier member, and at least one release layer of material removably covering the one or more adhesive layers. In one form, the adhesive mat includes a carrier sheet, first and second adhesive layers on opposing planar sides of the carrier sheet, and first and second release layers of material removably covering the two adhesive layers.
