Water Reducing Agent

ART-JR|Water Reducing Admixture in Large-Volume Concrete

ART-JR Set Retarding Type High Performance Water Reducing Admixture Description ART-JR is a newly developed green and environmentally friendly polycarboxylate-based high performance water reducing agents, PCEs, which improves the workability of concrete with high water reduction rate, low slump loss and good compatibility with cement. ART-JR helps to maintain good fluidity of concrete over a longer period and has the advantages of reducing the temperature rise in large-volume concrete, reducing shrinkage, and having no corrosion to steel reinforcement. It is particularly suitable for long-distance concrete transportation, construction of high-grade concrete, and concrete with retarding requirements in summer. Main Characteristics Water reducing rate can reach more than 25%, which meets the construction requirements of high-grade concrete Has a retarding effect, the slump of concrete is virtually lossless within two hours, and the initial and final setting times of the concrete can be extended by 2-3 hours according to construction requirements. Low air entraining performance; air content of concrete is less than 2%, which improves workability of concrete No corrosive effect on steel and improves the durability of concrete Applications Large-volume concrete and high-strength concrete construction under hot climate conditions Pumped, long-distance transportation, high-strength concrete and ultra-high-strength concrete Cast-in-place concrete, reinforced concrete, and prestressed concrete used in industrial and civil construction, roads, bridges, port terminals, airports, high-speed railways, and other engineering projects.
