Product Description
1. Introduction
Sea Resistance Cement is a kind of special material that can resistance corrosion of SO42-, Mg2+ and Cl- with
the high consistency of 30000mg/L for long. Sea Resistance Cement is widely used in the resistance corrosion
concrete construction for example seaport, salt field, ridge and culvert of railway, shotcrete in tunnel, especial
for the construction near sea.
2. Character
2.1 High Corrosion Resistance
Sea Resistance Cement can resistance corrosion of SO42-, Mg2+ and Cl- with the high consistency of 30000mg/L
for long.When the test specimen is marinated in the erosion solution for one year, the corrosion coefficient is
between 1.48 and 2.13. Its resistant corrosion more excels High Sulfate Resistance Portland Cement.

2.2 High Early Strength
Compressive Strength of Sea Resistance Cement at 1 day is near about 60% of compressive strength at 28 day age.
3. Quality
Specification according to Q/STF06-2004 Standard:
3.1 Fineness (residue of sieve on 0.08mm): 10% Max
3.2 Setting Time: Initial setting 30minutes Min, Final setting 4hours Max
3.3 Erosion Coefficient F6 (30000mg/L, SO42-): 0.80 Min
3.4 Compressive Strength: 25.0Mpa(1d) Min, 40.0Mpa(3d) Min, 52.5Mpa(28d) Min
3.5 Breaking Strength: 3.5Mpa(1d) Min, 5.0Mpa(3d) Min, 6.5Mpa(28d) Min
4. Application
4.1 Just like Ordinary Portland Cement, Sea Resistance Cement can be mixed with water and sand.
4.2 Sea Resistance Cement is widely used in the resistance corrosion construction for example seaport, salt field, shotcrete in tunnel near sea, intake aqueduct and offtake of sea water, road and bridge near sea, concrete project of resistancing SO42- and other kinds in saline and ground solied by salt.
4.3 If it is required for the construction, we can supply the related pumping aid, concrete retarder, antifreezer, corrosion-inhibiting admixture for Sea Resistance Cement.
4.4 When making the plain concrete, it is allowed to mix the Sea Cement with sea water.
specifications︰
1 Fineness (residue of sieve on 0.08mm): 10% Max
2 Setting Time: Initial setting 30minutes Min, Final setting 4hours Max
3 Erosion Coefficient F6 (30000mg/L, SO42-): 0.80 Min
4 Compressive Strength: 25.0Mpa(1d) Min, 40.0Mpa(3d) Min, 52.5Mpa(28d) Min
5 Breaking Strength: 3.5Mpa(1d) Min, 5.0Mpa(3d) Min, 6.5Mpa(28d) Min
Advantages︰
Sea Resistance Cement has good and high resistance corrosion and high early strength. Sea Resistance Cement can for long resistance the corrosion of SO42-, Mg2+ or Cl- with the consistence 30000mg/L. It has more better the character of resistance corrosion than High Sulfate Resistance Cement. Its compressive strength at 1day can reach 60% of compressive strength at 28day.
