H2 production under gamma irradiation of a calcium aluminate cement: an experimental study on both cement pastes and its stable hydrates

, 2021
International audienceThe objective of this paper is to investigate the use of calcium aluminate cements as alternative cements within the context of nuclear waste stabilization by solidification. Using an external 60 Co source, the effect of γ-radiation

Natural fiber-reinforced light-weight cement blocks prepared from waste for sustainable development

Acta Polytechnica CTU Proceedings, 2022
Low density of the light-weight cement blocks offers an advantage in terms of dead load reduction, which is advantageous in structural design-reduction of size and numbers of load-carrying structural components is possible.

Modifications in hydration kinetics and characteristics of calcium aluminate cement upon blending with calcium sulfoaluminate cement

, 2022
The present study explores the modifications in hydration kinetics and characteristics of calcium aluminate cement (CAC) upon blending with calcium sulfoaluminate (CSA) cement. CAC was replaced with CSA cement at 0, 30, 50, 70, or 100 wt%.
