Abstract: This guide reports data on the thermal properties of concrete and masonry constituents, masonry units, and systems of materials and products that form building components. This guide includes consideration of thermal mass of concrete and masonry, passive solar design, and procedures to limit condensation within assemblages. Keywords: aggregate; cement paste; concrete; concrete masonry unit; moisture; specific heat; thermal conductivity; thermal diffusivity; thermal resistance.
