Early age hydration of model slag cement: Interaction among C₃S, gypsum and slag with different Al₂O₃ contents

A deeper insight into SO₃/Al₂O₃ ratio including the contribution of alumina in slag at early age is required to ensure a properly sulfated slag cement. In this paper, to investigate the effect of gypsum and alumina of slag, emphasis was laid on the hydration characteristics of C₃S-gypsum-slag system...

PCM energy storage during defective thermal cycling

Incomplete thermal cycling affects storage capacities of phase change materials (PCMs). Existing PCM measuring methods are presented with their drawbacks. A new device named “the Capacity Cube” is designed to bypass these drawbacks. Both the Capacity Cube and PCM pouches are modelled to perform simulations on full thermal cycles and on...
