Concrete Bleeding Control with Polycarboxylate Superplasticizers
Polycarboxylate superplasticizers typically cause less concrete bleeding than traditional naphthalene- or aliphatic-based reducers. In rare cases, however, they produce more. When excessive bleeding does appear, adjustment becomes genuinely difficult. Molecular Structure Design of Polycarboxylate Superplasticizers Designers can limit bleeding through several molecular approaches. First, the superplasticizer lowers water demand while preserving workability. Less mixing water translates into significantly …
