Updates: Meeting with RISE
In a technical discussion, participants (RISE, Swerock, Heidelberg Materials, and LiU) delve into the complexities of reactivity in blended materials. The conversation covers the activation of alternative binders by cement, the significance of hydration, and the impact of temperature on reactivity. Experimental methods, including the use of an isothermal calorimeter, are discussed for measuring heat development over time. The team explores challenges related to different temperatures and optimal data analysis times. Various aspects of data analysis, such as compressive strength correlation and temperature effects, are examined. The discussion also involves the unexpected findings in environmentally friendly blended cement compared to traditional Portland cement, sparking interest in further investigation and model development. Overall, the dialogue showcases the depth of understanding required for studying material reactivity and its implications for concrete properties.
