The Science Behind Polycarboxylate Superplasticizer Powder’s Efficiency
The impressive performance of polycarboxylate superplasticizer powder boils down to its clever molecular design. Imagine a long polymer backbone with numerous shorter, negatively charged side chains sprouting off it. This unique architecture is key. The long chains physically push cement particles apart (steric hindrance), while the charged side chains (often carboxylates) attract water molecules, creating …
