Concrete admixtures
There are many different additives in concrete, some of which are desirable and even mandatory for use such as plasticizers, lubricants, washes. The rest can be used depending on your needs: dyes, fiber (reinforced fiber), curing accelerator, water repellents. More about each of them is written in the product description. And for now I want to mention that most additives for concrete like dyes, plasticizers, hardening accelerators and nerve, are calculated from the amount of binder test cement.
