· When a grinding aid comes in contact with a cement particle, it forms an instant gel around the particle. This gel hydrates the grain and initially serves as a barrier from other cement particles. With time, the gel crystallizes. This crystallization allows the cement particle to attach itself to others, forming a fluid lattice structure.

· A grinding aid is a specialty chemical agent used to make it easier to grind and mix cement. Specifically, grinding aids prevent cement particles from reagglomeration, or readhering, during and after the grinding process. Grinding aids make it possible to streamline the cementmaking process by increasing process efficiency and material fluidity. These benefits of cement grinding aid .
