What is it about?

This study analysed the behaviour of two laboratory-synthesised calcium silicates, C3S and C2S, after hydration in 8 M NaOH and in water as a control. The results showed that hydrating C3S in a highly alkaline medium had no significant effect on the mechanical development of the material, whereas in C2S hydration, that medium hastened hydration substantially, impacting setting and hardening times.

Why is it important?

This finding has technological implications, given the low early age reactivity of dicalcium silicate under normal hydration conditions.
