Structural Concrete, EarlyView.Abstract Incorporating metakaolin (MK) as a partial cement replacement offers a viable pathway to reduce carbon emissions while improving concrete performance. However, its durability behavior remains inconsistent, and the applicability of durability test methods to MK‐based concrete is not well established.

Hydration of calcium aluminate cement blended with anhydrite [PDF]
Advances in Cement Research, 2018 Calcium aluminate cements (CACs) are used in combination with calcium sulfates as binders in self-levelling mortars. The influence of commercial CAC/anhydrite ratio on the solid phase assemblage and pore solution at water to binder (w/b) ratios of 0·40 and 0·72 was investigated between 1·5 h and 91 d of hydration using a multi-method approach including

Structural Concrete, EarlyView.Abstract This study explores the potential of high‐volume amorphous silica (SiO2) replacement for ordinary Portland cement (OPC) in concrete to reduce carbon emissions. Amorphous SiO2, such as silica fume (SF) and CO2 mineralization‐produced Si‐rich gel, offers superior properties to concrete but is under‐researched for its use in concrete with high ...

Some observations on the calcium aluminate carbonate hydrates
, 1960 Two calcium aluminate carbonate hydrates, previously reported in the literature, were prepared and various properties determined. The compound 3CaOAl2O3CaCO311H2O, was prepared by precipitation from mixtures of solutions of calcium aluminate, calcium ...
