The most common grades of cement are: 1. Ordinary Portland Cement (OPC): This is the basic and most commonly used cement, which is used for general construction purposes. It has a strength range of 33-43 MPa (Mega Pascal). 2. Rapid Hardening Cement: This type of cement has a higher initial strengthRead more
The most common grades of cement are:
See less1. Ordinary Portland Cement (OPC): This is the basic and most commonly used cement, which is used for general construction purposes. It has a strength range of 33-43 MPa (Mega Pascal).
2. Rapid Hardening Cement: This type of cement has a higher initial strength than OPC, and provides faster hardening. It can be used in construction projects that require rapid setting and high early strength.
3. Low Heat Cement: This type of cement is suitable for construction which requires high quality and rapid setting. It has lower heat of hydration and decreased temperature rise.
4. Sulfate Resisting Cement: This type of cement is resistant to sulfates, chlorides and other chemicals, making it suitable for use in areas with high sulfate content in soil and groundwater.
5. Blast-Furnace Slag Cement: This type of cement is made from ground granulated blast furnace slag, which has lower carbon dioxide emissions and makes the cement more eco-friendly.
6. High Alumina Cement: This type of cement is used in areas where there is a need for high resistance to sulfates and other chemicals. It has a higher alumina content than OPC and provides better resistance to corrosion.
