Simulations and Measurement of Temperatures in Bridge Structures

Abstract:

Massive structures are exposed to the risk of high temperatures due to cement hydration. With the requirement for sustainable development, the clinker content of conventionally manufactured cements is being reduced, resulting in the development of blended cements, which are gradually being introduced into production. Therefore, the development of temperatures in massive concrete structures containing modern blended cement is the subject of an experimental program. Its results are evaluated not only in terms of the properties of the resulting concrete, but also in terms of the possibility of concrete production and the technology of mixing. Finally, recommendations are given for the design of concrete mixtures for massive structures. Furthermore, the article deals with the comparison of the measured values with the thermal analysis of the structures.
