Polycarboxylate superplasticizers contain sulfonic acid groups, carboxyl groups, and numerous branched chains, featuring low dosage, high water-reducing rate, and good retention properties. They can significantly increase concrete strength, reduce concrete shrinkage, and improve concrete durability. They have low alkali content and do not contain chloride ions or formaldehyde. They can be widely used in all concrete projects such as pumped concrete, self-compacting concrete, high-strength and durable concrete, and high-performance concrete.
