    Cement is a binder used in construction that sets and binds other materials together through a chemical reaction with water called hydration. There are various types of cement specified by standards organizations for different uses depending on properties like setting time or sulfate resistance. Cement production has environmental impacts from resource use and emissions, and direct contact with cement can cause health issues, though it is widely used in construction globally when handled properly.

    CEMENT

    Presentation by
    SAMRAT KHATRI
    CEMENT
    • A cement is a binder, a substance used for construction that sets, hardens,
    and adheres to other materials to bind them together.
    • Setting and hardening result from hydration, which is a chemical
    combination of the cement compounds with water.
    TYPES OF CEMENT
     Ordinary Portland Cement IS:12330:198
     Sulphate Resisting Cement
    IS:269:1989 8
    33 Grade
     Ordinary Portland Cement  Portland Slag Cement IS:455:1989

    USES OF CEMENTS
    • Rapid Hardening Cement: Where formwork is required to be removed early
    for re-use elsewhere
    • Sulphates Resisting Cement: Concrete to be used in foundation and basement,
    where soil is infested with sulphates
    • Quick setting cement: For concreting in static or running water.
    • Low Heat Cement: mass concrete construction like gravity dams
    • High Alumina Cement: is used in works where concrete is subjected to high
    temperatures, frost, and acidic action.
    • Portland pozzolana cement: Marine Structures, sewage works
    • White Cement: architectural purposes, interior and exterior decorative
    work
    • Hydrophobic cement: water structures such dams, water tanks, spillways,
    water retaining structures etc.
    • Rediset Cement: Precast buildings or industries
    PROBLEMS
    • The main environmental issues associated with cement production are
    consumption of raw materials and energy use as well as emissions to air.
    • Cement can cause ill health by skin contact, eye contact, or inhalation
    • Shrinkage may causes crack development and strength loss.
    • At end of life, concrete can be crushed and recycled but the recycled
    material cannot be used for new building concrete. Therefore, the scrap
    value of concrete is almost nil.
    SOLUTION
    • Use of Steel structure has been increasing globally.
    • The cement plant should be isolated from Residential area
    • Protective devices must be used while dealing with Cements
    CONCLUSION
    • Despite many problems, Cement is largely used all over the world
    • Different method of precaution should be applied while dealing with
    cement
    • Standard fixed by different codes like IS, BS, NBC should be followed
    strictly.
    • For different condition, Different type of cemnent with appropriate
    properties must be used.
