Question
Chapter 12, Problem 12.7PAE
Interpretation Introduction
Interpretation:
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.
