It is known in the literature that Calcium Carbonate content has influence on the mechanical & thermalproperties of PP / HDPE bags, used for packing cement at our works. It is observed that the tensilestrength,… Read More »Chemical procedure for estimating Calcium Carbonate content in HDPE bags at works
The SO3 determined in the cement is the sum of SO3 of the different constituents:• Clinker• Mineral components (Fly ash ,Slag etc)• Calcium sulfate added for finish grinding . The SO3 from the different constituents… Read More »METHOD TO OPTIMIZE THE SO3 IN THE CEMENT
The availability of limestone deposits containing lower MgO content (< 2 %) is slowly depleting and many cement plants are forced to accept limestone having higher MgO (> 3.0 %) for cement manufacture. Unsoundness problems… Read More »Raw Mix Optimisation with High MgO containing Limestone
