Lubrication effect: The hydrophilic group in the water reducing agent has strong polarity, so the water reducing agent adsorption film on the surface of cement particles can form a stable solvated water film with water molecules. This water film has good lubrication effect and can effectively reduce the sliding resistance between cement particles, thereby further improving the fluidity of concrete.…
