This is accomplished by addressing several challenges in the production of cement. For example, as cement grinding progresses and grains become smaller, the attractive thermodynamic, physical, mechanical and chemical forces result in strong adhesion of particles. This causes agglomeration (or clumping) of cement particles.

Cement is a commonly used binding material in the construction. The cement is obtained by burning a mixture of calcarious (calcium) and argillaceous (clay) material at a very high temperature and then grinding the clinker so produced to a fine powder. It was first produced by a mason Joseph Aspdin in England in 1924. He patented it as portland ...

Another option for smoothing a rough concrete surface is to apply a skim coat. You should never use regular concrete for this. Choose a product specifically made for skim coats, like micro-topping. This is a cement based mix that is meant to be troweled on 1/16" to 1/8" thick. If you have low spots, this is probably going to be the best method.

Step 6 : Finish Grinding. The clinker is ground in a ball mill—a horizontal steel tube filled with steel balls. As the tube rotates, the steel balls tumble and crush the clinker into a super-fine powder. It can now be considered Portland cement. The cement is so fine it will easily pass through a sieve that is fine enough to hold water.
