摘要:
A combination cracker dispenser and entertainment center is provided and consists of a housing that will contain a lazy susan tray near the bottom to hold crackers, a mechanism to dispense one cracker at a time, a dish near the top to hold dip therein to be used for the crackers and a built-in radio placed within a transparent middle portion of the housing.
摘要:
A concrete article comprised of concrete having therein a reinforcing fiber, where at least about 50 percent of the reinforcing fibers are frayed only at an end or ends of the reinforcing fibers, may be made by mixing concrete, water and a reinforcing fiber for a sufficient time to fray the ends of at least 50 percent of the fibers and curing the mixture to form the concrete article. The fiber may be a reinforcing fiber comprised of at least two filaments bonded together and the filaments being comprised of a polymeric core and a polymeric sheath comprised of a fusing-fraying polymer, such that the reinforcing fiber, when mixed with inorganic particulates, frays predominately only at an end or ends of the fiber.
摘要:
A monofilament plastic fiber useful in reducing plastic shrinkage cracking of concrete articles has been discovered. The fiber has a core that is a polyolefin that is at least partially enveloped by a sheath that is a copolymer of an olefin and at least one olefinically unsaturated comonomer selected from the group consisting of an unsaturated carboxylic acid, alkyl acrylate, alkyl methacrylate and vinyl ester.
摘要:
A concrete article comprised of concrete having therein a reinforcing polymer that has a surface comprised of a thermoplastic hydroxy-functionalized polyether or polyester. The concrete article is made by mixing concrete, water and a reinforcing polymer that has a surface comprised of a thermoplastic hydroxy-functionalized polyether or polyester and curing said concrete mixture forming the concrete article.
