The hydration of cement generates heat due to the exothermic nature of the hydration process. Poor heat dissipation in mass concrete results in a temperature gradient between the inner core and the outer surface of the element. High temperature gradients generate tensile stresses that may exceed the tensile strength of concrete thus leading to thermal cracking.
Eterpan is a medium density fibre cement sheet that is used for external cladding, base for stone and brick slips, soffits, decks, internal linings, flooring and rigid underlay. Manufactured with a flow on production process and then autoclaved at very high temperatures and .

In this process, the hydrated cement reacts with CO 2 in the air, slowly reversing some of the processes that took place in the kiln when the cement was made (this is the carbonation process; it also causes reinforcement corrosion, see Section ). It is estimated that this may reduce the carbon footprint of the cement industry by 3–5%.
