Thermal Mass
Thermal mass is a property that enables building materials to absorb, store, and later release significant amounts of heat. Early civilizations took advantage of thermal mass properties in stone and adobe construction to enable life in very hot and dry climates centuries ago. Buildings constructed of concrete and masonry have the same energy ...
Chapter 3
Typically, 15 percent to 30 percent of the portland cement is replaced with fly ash, with even higher percentages used for mass concrete placements. An equivalent or greater weight of fly ash is substituted for the cement removed. The substitution ratio for fly ash to portland cement is typically 1:1 to 1.5:1.
