DEA (Diethanolamine)
-
DEA (Diethanolamine) is a chemical compound that is a clear, colorless liquid. It is commonly used as a cement grinding aid in cement production because adding DEA to cement helps reduce the energy consumption required for grinding and enhances the resulting cement’s strength and quality.
DEA works by interacting with the surface of the cement particles during the grinding process. It acts as a surfactant, lowering the surface tension between the cement particles and the grinding media, which can consist of steel balls or other materials. This reduces the energy required to grind the cement, as less energy is needed to overcome the frictional forces between the particles and the grinding media.
In addition to reducing energy consumption, using DEA can also improve the strength and quality of the resulting cement. This is because DEA can increase the hydration of the cement particles, leading to a more complete and efficient curing process. This, in turn, can result in a higher compressive strength for the finished cement.
