TIP analysis is performed at the point of peak temperature, generally 18 to 24hrs post-concreting. [4] Measurements are available relatively soon after pouring (6 to 72 hours), generally before other integrity testing methods such as cross hole sonic logging and low strain integrity testing can be performed.
Creep and shrinkage of concrete are two physical properties of concrete. The creep of concrete, which originates from the calcium silicate hydrates (C-S-H) in the hardened Portland cement paste (which is the binder of mineral aggregates), is fundamentally different from the creep of metals and polymers.

For example, if 250 J of heat energy is added to a copper gear with a thermal mass of 38.46 J/°C, its temperature will rise by 6.50 °C. If the body consists of a homogeneous material with sufficiently known physical properties, the thermal mass is simply the mass of material present times the specific heat capacity of that material.
