  1. OPC is a general purpose Portland cement suitable for all uses where the special properties of other types are not required. It is used where cement or concrete is not subject to specific exposures, such as sulfate attack from soil or water, or to an objectionable temperature rise due to heat generated by hydration. Its uses include pavements and sidewalks, reinforced concrete buildings, bridges, railway structures, tanks, reservoirs, culverts, sewers, water pipes and masonry units.

  2.  

    Due to the light color of Limestone Cement it is preferable to use in wall plaster and also in tile manufacture and tile fixation, Moreover Limestone is preferable for use in the manufacture of bricks and in brick fixation. 
    The composition of Portland Limestone Cement shall be as follows:

    • Portland clinker 65 to 79%
    • Limestone 6 to 20%
    • Minor additional constituents    

     

  3. Slag Cement is a promising type of cement due to its property of having sulfate and chloride resistance. It can be used in marine environments because of this. Slag Cement also has low heat of hydration compared to Portland Cement so it can be used in massive concrete structures. Slag Cement can also be used successfully in pavement construction due to its high abrasion resistance.    

  4. Sulfate-Resisting Cement is used only in concrete exposed to severe sulfate action - principally where soils or groundwater has high sulfate content. It is specified with low Tricalcium Aluminate (C3A) content, generally less than 3.5%, as required when high sulfate resistance is needed.

Industrial ecology

How to create value from waste

Large amounts of natural resources, particularly minerals and fossil fuels, are used to manufacture cement. For many years the Group has been working to reduce the environmental impact of its activities by finding ways to obtain value from waste products
