Abstract Low‐carbon supersulfated cements (SSC) are promising binders for reducing CO2 emissions because they contain high amounts of slag and only minor clinker. However, their practical use is still limited by slow early‐strength development and sensitivity to chemical admixtures.

Carbonation of MgO‐Nesquehonite Cements
ABSTRACT MgO‐based binders containing hydrated magnesium carbonates are promising low‐carbon materials due to their ability to store CO2 during hardening and carbonation. This study investigates MgO‐nesquehonite (MgCO3ˑ3H2O) binders containing 0, 20 and 40 mass‐% of nesquehonite hydrated in N2‐filled desiccators or at 4 vol‐% CO2, as well as hydration ...

Compatibility of Slag-Blended Cement with Polycarboxylate Ether Superplasticisers: Rheological Properties Study [PDF]
The compatibility of slag blended-cement (SBC) with superplasticisers was investigated using rheological measurements. Accordingly, continuous flow tests and thixotropic behaviors were studied for different ages of hydration.

ABSTRACT Workability control of alkali‐activated binders (AABs) remains an obstacle to producing low‐carbon clinkerless ultra‐high‐performance concrete, as their formulation usually necessitates low water‐to‐binder (W/B) ratios, high binder content, and concentrated activator solutions. To address this challenge, a greener and more manageable composite
