There are a number of additives that can be added to the batch during the mixing process. Some of them help increase the strength of the finished concrete. Another class of additive will effect the look of the finished product. Strength: Concrete additives such as fiber are added to the dry ingredients to help produce a stronger concrete.Concrete Additives & Mortar Color | TLC Supply - Hardscape,,Silpro Concrete Supplement: An integral admixture that reacts with Portland cement in concrete, mortar, stucco and grout to produce complete hydration.
