High Silicate Silicate Cement HSR
Medium-heat, low-heat and low-heat slag Portland cement is mainly used in foundation and
underwater engineering of water conservancy dams, large buildings and large buildings.
Real Effect Presentation
The use of sulfate resistant cement will achieve better corrosion resistance.
Certain unique properties of special cement, suitable for specific requirements of the use, or can
play a special role and give special functions to the building cement varieties.
State-owned Large Modern
Cement Production Enterprises
According to the sulfate resistance experiment of cement test block conducted by our technology r&d center, the
general cement test block is seriously eroded, and the change of sulfate resistance cement test block is not obvious.
(2) high late-stage and long-term strength enhancement rate.
This kind of sulfate resistant cement is suitable for construction of projects below sea port, water conservancy,
underground and underground water level which are corroded by sulfate. For example, concrete construction in
cangzhou area with high concentration of saline-alkali and sulfate ions or chemical plant area.
In underground are rich in sulfates in the coastal and
inland areas in China, because of the erosion by
sulfuric acid root ion, concrete structure situated in
loose and soft, gradually lose strength concrete cause
breakup, cause damage to property and safe hidden
trouble, in order to ensure the durability of concrete
engineering, in addition to adopt proper concrete
technique measures, should also use sulfate resistant
Portland cement; The engineering environment of
saline-alkali land is complex, and the construction site
contains a lot of rock salt, glauber salt, gypsum and
other soluble salts.
(1) good sulfate resistance. According to the national
standard, the linear expansion rate of sulphate resistant
cement at 14d should not be greater than 0.060%, while
that of high sulfate resistant cement should be 0.04%,
and the linear expansion rate of sulfate resistant
Portland cement produced by our company is 0.021%.
