THERMAL EFFECTS ON MASONRYTHERMAL EFFECTS ON MASONRYAll materials are inherently sensitive to fluctuations in temperature. Construction of structure usually takes place under normal temperature conditions. However, ambient temperatures may vary widely, cyclically, between summer and winter, by as much as 100°F between the two extremes. As a result of temperature changes, most materials expand (when the temperature rises above normal) and contract (when the temperature falls below normal). These thermal characteristics are described by a property called coefficient of thermal expansion. Table 3.9 lists coefficients of thermal expansion for some of the common building materials.
