ART-JR2
Set Retarding Type High Range Water Reducing Admixture
Description
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.
Main Characteristics
Provides an ultra-high water reduction rate
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
Increases both early and later strength of concrete, reducing the risk of shrinkage and cracking
Suitable for various cement and admixture systems, adaptable to different construction conditions and technical requirements
Applications
Ready-mixed concrete
Mass concrete
Pumped concrete
Precast concrete elements
