Description
During decades, calcium cements had been studied as a simple case to study hydration of more complex multiphase cements such as Portland cement, due to its very quick hydration and apparent simple chemistry. The strong dependence of temperature on mechanical strengths development was quickly noticed with unexpected regression of mechanical strength with time when initial hydration proceeds at low and room temperature.
A significant amount of studies were run since, with different curing conditions, sample sizes and analyses of hydrates (DTA, DTG, XRD, microscopy, synchrotron …). Temptative models were proposed to describe hydration and strength development.
This paper provides an approach to combine data science (statistical tools), old experiments (data) and scientific descriptors (models from literature) to assess hydration and its impact. This approach could be useful for other blends of cements used in oil well industry, when temperature profile could have a significant impact on hydrates stability.
