Magnesium-Containing Slurry as Technogenic Alternative Raw Material for Magnesium Oxychloride Cement [PDF]
, 2019 It has been shown experimentally that a waste of magnesium metal production is a realistic alternative to naturally occurring cement raw materials. The waste is the carnallite slurry forming during the chlorination stage.

Stability criterion for fresh cement foams [PDF]
Cement and Concrete Research (2019) 125, p105865, 2019 We prepare and study cement foam samples with well-controlled structure, i.e. containing monodisperse bubbles. We observe that the foam structure often changes before cement setting and identify ripening as the major destabilization mechanism at stake.

Influences of chloride immersion on zeta potential and chloride in concentration of cement-based materials [PDF]
, 2015 In this paper, the zeta potential of freshly mixed cement paste and hardened cement pastes, as well as the concentration index, was measured. The influences of chloride concentration in mixing water and slag content on zeta potential of freshly mixed ...

Setting control of completely recyclable concrete with slag and aluminate cements [PDF]
, 2016 A completely recyclable concrete (CRC) is designed to have a chemical composition equivalent to the one of general raw materials for cement production. By doing so, this CRC can be used at the end of its service life in cement manufacturing without the ...

Mortar and concrete based on calcium sulphate binders [PDF]
, 2006 In this study both hemi-hydrate and anhydrite are tested as calcium sulphate binders for structural mortar and concrete. The advantage of using calcium sulphates instead of cement as a binder is the fact that the production of calcium sulphate is more ...
