The effectiveness of polycarboxylate ethers comes from their unique mode of action. When added to a concrete mixture, PCEs reduce the viscosity of the cement paste by acting as dispersants. They achieve this by adsorbing onto the surface of cement particles, creating a negative charge that causes the particles to repel each other. This electrostatic repulsion minimizes particle agglomeration, leading to better dispersion and improved workability of the concrete.
