AC-A-S-H gel
BC-S-H gel
CEttringite
DPortlandite
Answer & Solution
Correct answer: B. C-S-H gel
1. §1.6: 'It has been said that the significant product of hydration is (CaO SiO2 H2O) which for simplicity sake is called Tobermorite Gel, because of its structural similarity to a naturally occurring mineral Tobermorite.
It is referred, commonly as C-S-H Gel.'
2. The porosity of this gel is about 28 percent and its specific surface is of the order of 2 million sq cm per gram of cement.
