Stains and dyes are used to brighten up basic gray concrete finishes. They consist of powdered or liquid additives that can be mixed in with the wet concrete or applied to the finished surface. Staining can be used to give concrete a highly textured look or to mimic the look of marble and other types of stone.
Often, additives (such as pozzolans or superplasticizers) are included in the mixture to improve the physical properties of the wet mix or the finished material. Most concrete is poured with reinforcing materials (such as rebar) embedded to provide tensile strength, yielding reinforced concrete.
