ART-JR2 is a concrete superplasticizer with retarding functions, specifically designed for various concrete engineering applications, especially for situations requiring extended initial setting times. By optimizing the molecular structure, this product enhances the dispersion ability with cement particles, effectively improving the workability and strength of concrete.
Provides an ultra-high water reduction rate.
Can be used in combination with other polycarboxylate high-performance water-reducing agents, air-entraining agents, and other conventional additives to achieve different effects.
Extends the initial setting time of concrete, suitable for long-distance transportation or high-temperature construction environments.
Enhances the flowability and pumpability of concrete, improve segregation and bleeding phenomenon.
Enhances the flowability and pumpability of concrete, improve segregation and bleeding phenomenon.
Suitable for various cement and admixture systems, adaptable to different construction conditions and technical requirements.
