As healthy dishes can only be made from healthy & fresh ingredients, quality cement can only be made from quality limestone. Dissatisfied with the poor limestone available – substandard in the amount of Calcium Oxide while often containing high levels of Magnesium Oxide – we at Sarbottam Cement have purchased various mines in limestone rich Palpa & Chitwan districts. These mines make available to us some of the finest limestone in the country, and as a result, we are able to deliver to our customers the highest quality cement possible.
Understanding that the majority of our cement is utilized in earthquake prone areas, Sarbottam Cement is uncompromising when it comes to strength and quality. In fact, we here at Sarbottam Cement have pledged to provide cement that all our customers can trust. Our energy efficient production methods coupled with our high quality raw materials means that our cement just cannot be beat – not by other manufacturers, nor by harsh elements & natural disasters.
Though equipped to produce Portland Pozzolana Cement (PPC) at various blaines, currently Sarbottam cement actively produces Sarbottam Green Ordinary Portland Cement™ (OPC) and Sarbottam Shree Green Portland Slag Cement™ (PSC).
Unmatched in quality, our cement has been used in a wide variety of projects, such as:
To mitigate unnecessary environmental strain, we carefully mix the Ground Granulated Blast-Furnace Slag (GGBS) – obtained as a byproduct when manufacturing steel – with clinker and gypsum in the cement mill.
As a result, Sarbottam Shree Green PSC Cement™ is more resistive against cracking caused by thermal shrinkage & heat of hydration without compromising quality and our environmental commitment.
Compared to other PSC manufacturers, Sarbottam Shree Green PSC Cement™ is:
