Reaction with cement and lime Portland cement
consists of about 80% calcium silicates: alite
S) and belite
These will react with water according to the following reactions.
S + 3H = CSH + 2 CH
S + 2H = CSH + CH
The final structure consists of about 75% calcium silicate hydrate
(CSH) and 25% hydrated lime (CH).
The hydrated lime (CH) also called calcium hydroxide
or Portlandite will react with pozzolana, forming
CH + S -> CSH gel-like structures
CH + S + A -> C2
