Abstract:
Understanding and predicting the thermal behavior of mass concrete can help designers and contractors reduce the probability of crack formation, thus helping to ensure concrete durability. However, reliable simulation models are rather impractical to implement for preliminary investigations, which demand quick calculations. From a practical perspective, rough estimates of mass concrete temperature could be used to guide preliminary mixture design while avoiding complicated calculations. The nomogram developed by the authors allows predicting a preliminary estimate of the maximum temperature achieved in mass concrete structures by taking into account mixture composition and ambient conditions. It is also available as a mobile app in both SI and U.S. customary units.
