Sep 14, 2008. #3. If you're using anything but a mixer made of heavy duty steel, you'll end up with dents. I did the same thing many years ago, using large bolts and nuts, and produced a very dented mixer, although it did work quite well. I would think twice before renting the mixer, because you may end up buying it.

Now a days Cement plants are producing 75–80% PPC & 20–25% OPC due to high market demand of PPC. Production of PPC is cheaper and it's market rate is also lower than OPC by nearly 25 rupees per bag, so general consumer are attracted towards PPC cement. Cement companies also want to produce more and more PPC grade.
