Some Problems In The Application Of Polycarboxylate Superplasticizer(IV)
Compatibility of polycarboxylate superplasticizer with other admixtures polycarboxylate superplasticizer and many superplasticizers cannot be mixed and compounded in any proportion like naphthalene and aliphatic superplasticizers. For example, the negative effect on plastic slump retention is th...Read more -
Some Problems In The Application Of Polycarboxylate Superplasticizer(III)
Dosage and water consumption of polycarboxylate superplasticizer: Polycarboxylate superplasticizer has the characteristics of low dosage and high water reduction. When the dosage is 0.15-0.3%, the water-reducing rate can reach 18-40%. However, when the water-to-binder ratio is small (below 0.4), ...Read more -
Some Problems In The Application Of Polycarboxylate Superplasticizer(II)
The influence of the mud content of sand on the polycarboxylate superplasticizer is often fatal, which is more obvious than the naphthalene series and aliphatic superplasticizers. When the mud content increases, the workability of conc...Read more -
