The cement sector is at an important point among the productions that harm the environment. Cement production should be performed in a controlled manner due to the energy consumed and greenhouse gases released to the environment [, , ]. A large part of this energy is spent during the clinker grinding process.
How to Concrete Grinding [3 Methods,11 Steps,Cost Overview]
22-02-2021· Concrete grinding cost depends on the area you are working on and the geographical location of course. Source: homeguide. Usually, it may cost you around 3$ to 12$ per square foot to polish concrete. Usually, the cost of dry grinding of concrete is more expensive. On the other hand, wet grinding of concrete is cheaper.
