Impact of sodium gluconate on white cement-slag systems with Na2SO4

Karen Scrivener, Berta Mota Gassó, Thomas Matschei

Sodium gluconate has been shown to compensate the impact of alkalis on the long term strength development of cement pastes. This work studies the impact of sodium gluconate combined with Na2SO4 on the microstructural development of white cement-slag system ...

The influence of sodium salts and gypsum on alite hydration

Karen Scrivener, Berta Mota Gassó, Thomas Matschei

This work aims to clarify the impact of alkali and sulfate on the hydration kinetics and microstructural development of alite. The plain alite system is compared to systems with addition of: i) gypsum, ii) Na2SO4, iii) NaOH plus gypsum and iv) NaOH. In all ...

Impact of alkali salts on the kinetics and microstructural development of cementitious systems

Berta Mota Gassó

Supplementary cementitious materials (SCM) lower the environmental impact of cement and concrete but react more slowly than Portland cement, which therefore limits the levels of substitution possible as reasonable early strengths are necessary. One of the ...
