PRODUCT DESCRIPTION
Set Retarding High Range Water Reducing Admixture (RHW™) is an advanced solution to optimize concrete performance. This admixture is formulated with cutting-edge technology and combines the benefits of set retardation, high-range water reduction, and improved workability.
RHW™ is based on a polycarboxylate polymer, ensuring excellent compatibility with various cementitious systems. Its unique mechanism of action involves dispersing cement particles within the concrete, resulting in enhanced flowability and ease of placement.
By effectively reducing the water-cement ratio, our admixture significantly improves concrete’s compressive strength and durability. It also offers extended setting time, allowing for more flexible construction schedules and reducing the risk of premature hardening.
The RHW™ is specifically designed to meet the requirements of ASTM C494, ensuring consistent performance and reliability. Furthermore, it is free from chloride and other corrosive substances, safeguarding the integrity of steel reinforcement.
Our Set Retarding High Range Water Reducing Admixture is a trusted choice for a wide range of applications, including high-performance concrete, precast elements, ready-mix concrete, and more. Its superior performance characteristics enable efficient construction practices, reduce costs, and deliver exceptional quality and longevity concrete structures.
