2010-1-1 The tested cement properties include water demand, Blaine fineness, sieve residue, setting time and compressive strength. The results showed that the use of higher concentrations of GAs can lead to significant improvements in the performance of grinding mills characterised by higher Blaine and lower sieve residue values.

2018-8-1 In fine grinding of cement in a ball mill, it is sometimes impractical to grind finer in a dry state. Even though the chemical reactivity requires the material to be dry ground, it is sometimes necessary to use different breakage machines to obtain the product, but it is usually more expensive, requires more energy and reduces capacity. The economic alternative is to use a grinding aid.

2019-10-3 Concrete chipping is a mechanical process practiced in the construction industry in order to increase adherence to smooth surfaces. It is carried-out before plastering of beams, columns and other concrete structures with smooth surfaces. The objective of this project was to design a low-cost concrete chipping machine suitable for the construction industry. An initial study was conducted to ...

The use of grinding aids in both open and closed circuit systems will improve the control of the grinding process, increasing the Blaine number (finer product). These advantages usually justify the cost of a grinding aid. But some cement manufacturers refuse to use grinding aids for economic reason.
