Q1 - True or False
1- Increase C3s→ Low early strength cement.
2- Higher heat of hydration → high sulfate resistance cement.
3- Absorbed water is the water molecules inside the layers of C–S–H gel
4- For marine structure, a cement that is high sulfate resistance and lower
ettringite are needed.
5- Low-heat Portland cement has less C2S and more C3S
