Abstract: The present invention discloses an improved paperboard for use in food or non-food products. The disclosed board utilizes a novel method of applying adsorptive material to packaging paperboard to overcome emissions (by adsorption thereof) of odiferous manufacturing components from the board, as well as any offensive odors emitted by contents of packages made from the board. The disclosed approach utilizes known adsorptive materials, which are applied to the pulp stock in such a manner that it does not negatively impact either the appearance or physical attributes of the finished board.

Abstract: A hydraulic cement mix including hydraulic cement, aggregate, sufficient water to effect hydraulic setting of the cement, and a polyamidoamine additive, the additive being present in an amount sufficient to increase the bonding strength of the hardened mix. Generally, the additive is present in a total amount of about 0.025 to 0.25% by weight based upon the weight of the cement, preferably in an amount in the range of about 0.075 to 0.15% by weight.
