ABSTRACT:
A device comprising a solid or powdered concrete admixture contained in a water-soluble container such that when the container and its contents are introduced into a wet mixer and agitated for a period of time, the water-soluble container is dissolved and the contents are released into the wet mixer. A separate water-insoluble receptacle is used to house and store the water-soluble container and its contents. In addition, there is disclosed a method for modifying the properties of a concrete by introducing a pre-weighed amount of solid admixture contained in a water-soluble container into a wet mixer and thereafter agitating the resulting mix.
