In curing cement plasters water is sprinkled from time to time. This helps in
keeping it cool
developing interlocking needle-like crystals of hydrated silicates
hydrating sand and gravel mixed with cement
converting sand into silicic acid.
As we learnt in
Oxide of Silicon -
SiO2 form three dimensional network
- wherein
Due to lack of formation of with oxygen
Water helps in hydration of calcium aluminates and calcium silicates which change in to their colloidal gets by developing interlocking needle like crystals of hydrated silicates.
