ART-RD180 is a super early-strength polycarboxylate water reducer which has an extremely high water reduction rate and can significantly shorten the setting time of concrete mixtures and promote the early strength development of concrete mixtures. ART-RD180 has a special molecular structure, which achieves self-assembly effect through pH response and temperature response mechanisms, enhancing the wetting effect on the surface of cement particles. While obtaining excellent fluidity, it greatly promotes the hydration process of cement-based materials.
ART-RD180 can be used for various concrete mixtures, especially suitable for precast components and other concrete mixtures with early strength requirements. It has extreme water reduction ability, excellent fluidity, moderate cohesion, ensuring excellent workability while enhancing the compactness of concrete mixtures.
It can provide a maximum water reduction rate of over 50%, and the dosage can be adjusted according to actual applications to meet the water reduction requirements on site.
It is compatible with other additives and can be used in combination with conventional additives such as delayed-release polycarboxylate dispersants, retarders, and air-entraining agents to achieve different effects.
The early strength (1 day) is increased by more than 40%.
Suitable for Portland cement and calcium sulfoaluminate cement.
Excellent plasticizing and water-retaining properties (for pumping or bucket conveying).
Improves shrinkage and the creep of concrete.
Rapid adsorption reduces competitive adsorption interference.
