Using polycarboxylate-based superplasticizer high performance water reducer as an admixture for high-performance concrete, it exhibits high water-reducing performance even at a low dosage. Experiments have shown that the polycarboxylate-based high-efficiency water reducer can significantly reduce the viscosity of concrete and effectively control the slump of concrete. The use of polycarboxylate-based superplasticizer high performance water reducer has a certain retardation effect on concrete setting. Comparative experiments have found that the setting time of concrete using polycarboxylate-based superplasticizer high performance water reducer is longer than that using sulfonated naphthalene-based superplasticizer high range water reducer. After 28 days, the concrete strength of using polycarboxylate-based superplasticizer high performance water reducer is more than 10% higher than that of using sulfonated naphthalene-based superplasticizer high range water reducer. The experiment also proves that when using polycarboxylate-based superplasticizer high performance water reducer, adding defoamer at the same time can reduce the air content of concrete and improve the strength of concrete.

In the field of concrete admixtures, with the continuous emergence of new materials, the market products have become increasingly diverse. However, there is a "veteran" that still holds a position in numerous construction projects - it is the naphthalene-based high range water reducer.
