Ghent cement plant (Credit: Heidelberg Materials Benelux) Heidelberg Materials Benelux started the batch production of calcined clay at its Ghent cement plant in Belgium. The calcined clay is for the production of Q-CEM, which shall pace the way for the production of low-carbon cements. Q-CEM ...

The decarbonation efforts of the cement industry in the past decades have led to a huge number of innovations of alternative binders with mixed, and for many times, confusing names. This communication provides an overview on the differences of reaction mechanisms of recently fast-developing and wide...

In a high-volume (50 wt.%) spodumene lithium slag (LS)-blended cement system, a polycarboxylate ether (PCE)-stabilized C-S-H nano-seeding accelerator (C-S-H-PCE) was introduced to improve the early-age mechanical properties. The effects of C-S-H-PCE on workability, early strength, and hydration...

This study investigates the use of recycled rubber (RR) and recycled plastic (RP) as partial replacements for natural sand in self-compacting concrete (SCC), with the objective of improving sustainability while maintaining satisfactory fresh-state behaviour. An experimental program was carried out ...
