  • Patent number: 11220458
    Abstract: A concrete composition and method include a portion of fine aggregate bearing a coating of a polymer or an admixture, which may be a continuous coating layer or a layer of powdered, discrete particles embedded in a binder. The polymeric coating may be an admixture in powdered form, a super absorbent polymer (insoluble in water, but absorbing water), or another polymer such as the acrylamides, co-polymers thereof, polyacrylamides, or the like (soluble in water). The coating absorbs water, but particles are too small to form significant voids. Water is absorbed into the concrete mix in far greater proportions (e.g. w/c ratio over 0.5) improving workability, doubling workability time, and improving ultimate compressive stress (strength).

  • Patent number: 11198650
    Abstract: A sheet 100 of water-soluble material such as polyvinyl alcohol comprises a plurality of individual, sealed pockets 110, each containing concrete admixture. The sheet is cut to size and attached to the interior of a formwork structure 200 with, for example, PVA glue. After concrete is poured into the formwork, covering the sheet 100, the sheet dissolves, releasing the admixture onto the surface of the concrete as it sets. In another arrangement, a sealed container 300 formed from a water-soluble material contains concrete admixture. The external wall of the container has a plurality of regions 320 where a thickness of the wall is reduced. The container is attached to interior walls of a formwork structure 200 or to reinforcing bars inside a formwork structure. After concrete is poured into the formwork, submerging the container, the container dissolves, with the thinner regions dissolving sooner, releasing the admixture into the concrete.

  • Patent number: 11186754
    Abstract: A hydrogenated petroleum resin, and a manufacturing method and use thereof, are provided. More specifically, a hydrogenated petroleum resin manufactured by subjecting dicyclopentadiene and an olefinic monomer to thermal polymerization and then carrying out a hydrogenation reaction, and a manufacturing method and use therefor are provided. The hydrogenated petroleum resin has the advantage of being useful in practical applications, since the petroleum resin is manufactured via thermal polymerization using inexpensive raw materials and on the contrary to conventional catalytic polymerization, a catalyst elimination process can be excluded. The hydrogenated petroleum resin produced in this way can be applied to, for example, an adhesive agent used in environmentally friendly sanitary goods, because the petroleum resin has excellent compatibility, adhesiveness and heat resistance, and has no bad odor.
