- To be suitable
- Prevents the corrosion of sea weter
- To be against the destruction of chemicals
- To be against the alkali – aggre gate reaction
- Increases the compressive strength
- Inproves the duarbility of concrete
- Avoids the thermal cracking
- To be able to water – proof highly

Characteristics of Cement Product
- High fineness
- Greyish green – black
- Quickly initial strength establishing rate
- Setting time: Starting for about 120 – 170 minutes
Ending after 3 – 4 hours
- Suitable for quick formworks dismantling works
- Quality is always ensured to be stabilized. Especially, Cement strength is always in over-graded excess that to be of great advantage to the users.
- High sulfate strength is to be of more advantage to Construction of underground, underwater works. Heat emission during setting is low that to be favorable for casting of mass concrete.

Instruction to maintenance of cement
- It is the best to use cement right after being transported away from plant.
- It should avoid the humid environment penetrates into cement.
- Requirement for the warehouses’ ground is to be in high, dry place which can avoid rainwater.
