Polycarboxylate high-efficiency water reducer is a new generation of environmentally friendly acid ether water reducer. Its molecular main chain is adsorbed on the surface of cement particles, which can effectively hinder hydration and enhance its flow retention ability. The branch chain is surrounded by cement particles, which plays a dual role of steric hindrance and electrostatic repulsion, so it has a good dispersion and water reduction effect.
