Hot and Cold pHun Experiment: Cement Hydration and pH Evolution During Curing

The Materials Science and Technology Teacher's Workshop (MAST) provides this lesson plan for students learning about concrete. The class will "calculate the amount of water that reacts during hydration when cement becomes concrete under differing curing temperatures and observe the pH change that occurs in the curing process." The procedure is designed to be spread across three class days. Discussion questions and teacher notes are included as well as a chart for data input.
