GL and CEM are two different types of cement used in construction. The main differences between them are as follows:
Below are the main Differences between GL and CEM
- Composition: GL or General Use Portland Cement is made primarily from limestone, clay, and gypsum, whereas CEM or Portland Cement is made from clinker (a material obtained from heating a mixture of limestone and clay), gypsum, and sometimes other materials such as fly ash or slag.
- Strength: CEM generally has higher compressive strength than GL, making it better suited for use in high-stress applications such as bridges and highways.
- Setting time: GL typically has a shorter setting time than CEM, which means it hardens more quickly. This can be an advantage in certain applications where rapid setting is desired.
- Environmental impact: CEM is considered to be more environmentally friendly than GL, as it requires less energy to produce and produces less carbon dioxide emissions.
- Cost: CEM is generally more expensive than GL due to its higher strength and other desirable properties.
Overall, the choice between GL and CEM will depend on the specific application and the desired properties of the cement.
