The result of spraying a solution of phenolphthalein on the surface of a piece of old concrete should be explained. Concept Introduction: Concrete is a mixture of cement, water and other additives that are mixed in order to produce concrete with the desired composition and characteristics. Hydration is a process through which water is added to the cement mixture to form silicate hydrates and calcium hydroxide, which makes concrete alkaline. Phenolphthalein is an indicator that is used to the test the extent of carbonation in concrete.
