Computational analysis of thermal processes at early-age hydration of lime-based binders
Original language description
Being used very frequently, calorimetric techniques face several challenges to deal with. A substantial signal delay within the initial period of measurement, which is even more significant in case of large volume calorimeters, belongs to the most important ones in that respect. In this paper, a computational technique for correction of experimental data is applied for early-age hydration of two lime-ceramic binders. The method utilizes an exact computational replica of the real experimental device that is able to follow the ongoing heat processes inside the calorimeter, producing undistorted outputs. The results presented within this paper show that internal parts of the calorimeter may absorb a significant part of heat released as the experimentally detected heat power peaks are ~7-9 times lower than their computational representations. The reliability of results is proved by a combination of sensitivity and uncertainty analyses.
