Fatty Acid-Based(Deep) Eutectic Solvents ThermodynamicBehavior and Thermal Properties for Low-Temperature Thermal EnergyStorage

Abstract The mismatch between heat supply and heat demand can be resolved by better utilization of low temperature waste heat with the help of low-temperature thermal energy storage (TES). In this work, binary mixtures of thymol (THY) with decanoic acid (C10), undecanoic acid (C1...

Thermal activation and pozzolanic reactivity assessments of Estonian clays for cementitious applications

Abstract This study evaluates the pozzolanic reactivity of locally sourced Estonian clays as supplementary cementitious material (SCM) alternatives. Two selected clays, Arumetsa (ARC) and Aseri (ASC), were calcined in a rotary tube furnace at three distinct temperatures (750 °C,...
