| dc.description.abstract | The increase in temperature of developing concrete as a result of heat liberated by cementing reactions is the
primary cause for thermally induced cracks in large concrete elements. It is very essential, in engineering to
predict the temperature rises in order to be able to minimise the potential of crack formation. This thesis covers
the experimental determination of the heat of hydration curve using the adiabatic calorimeter and experimental
determination of transient heat transfer obtained from measurement of temperature variations in concrete at its
early ages of hydration. The measured temperature profiles from a one-dimensional heat transfer scenario are
then compared with the predicted temperature profiles.
The adiabatic hydration curve of a concrete beam sample is used as input into a numerical technique known as
the Green Element Method for the calculation of temperature profiles. Time-based boundary conditions are
imposed on the equation governing the model and will be solved using the Green Element Method coded in
Fortran Power Station 4.0. | en |
