ABSTRACT:
The present invention relates to a method for modifying the properties of a concrete by introducing a solid admixture, contained in a paper package, into a fresh concrete, said solid admixture being selected from the group consisting of air-entraining admixtures, air detrainer admixture, accelerating admixture, alkali-reactivity reducer, superplasticizer, pumping aids, water-reducing admixture, corrosion inhibitor, permeability reducer, fibers, and mixtures thereof; and mixing the fresh concrete in a batch type mixer for sufficient time to cause the packaging material to disintegrate and distribute the admixture relatively uniformly throughout the fresh concrete.
