Abstract: Disclosed are compositions for anchoring materials in or to concrete or masonry. The compositions preferably comprise alkylacrylate ester monomer and a copolymer of alkylacrylate ester and methacrylic acid monomers, and free-radical catalyst.

Abstract: A high strength film/board lamination is formed from a cross-oriented laminated film and a corrugated layer. The cross-laminated film is formed from a first oriented plastic layer and a second oriented plastic layer in which the orientations of the plastic layers cross at an angle between but not equal to zero degrees and 180 degrees relative to one another. The cross-oriented laminated film is adhered to the corrugated layer in a noncontinuous manner. A method of forming a high strength lamination and a method of improving tear resistance in corrugated paper or paperboard based materials are also disclosed.

Abstract: Disclosed are methods for anchoring materials in or to concrete. The methods preferably comprise delivering to the concrete or masonry, the material to be anchored to the concrete or masonry or both an anchor composition comprising alkylacrylate ester monomer and a copolymer of alkylacrylate ester and methacrylic acid monomers, and free-radical catalyst.

Abstract: A screen for anchoring a fastener to a hollow block or brick wall which includes an elongate tubular plastic screen member having first and second opposite ends and a uniform diameter along its length. The first end is formed substantially into a frusto-conical shape that includes at least a portion thereof where the mesh of the screen is closed off. At least one reinforcement member is formed along the length of the elongate screen member that enables the elongate screen member to be inserted within a first aperture formed in a first wall of a hollow block and maintain the desired stiffness of the tubular screen member so that it can extend across the interior of the hollow block for blind insertion into a second aperture formed in a second opposite wall of the hollow block.
