Set Retarding Normal Water Reducing Admixture

The Set Retarding Normal Water Reducing Admixture, also known as RNW™, is an additive that serves as a plasticizer, water reducer, and concrete retarder. It is primarily composed of lignosulfonate, and its mode of action involves the distribution of cement particles within the concrete. By incorporating this plasticizer into the concrete mixture and reducing the water-to-cement ratio, the compressive strength of the concrete is enhanced. Furthermore, the RNW™ additive contains a combination of materials that act as retarders, thereby slowing down the setting time of the concrete. This characteristic proves beneficial in preventing cold joints during bulk concreting. In addition to its mentioned features and applications, RNW™ offers the advantage of minimizing the risk of cold joints during the concreting process.


PRODUCT DESCRIPTION

The RNW™ Set Retarding Normal Water Reducing Admixture is a highly effective concrete additive designed to enhance the performance of concrete. This innovative product is based on lignosulfonate, providing the combined benefits of a plasticizer, water reducer, and retarder. RNW™ meets the stringent requirements of the ASTM C494 standard, ensuring its reliability and consistency.
The mechanism of action of RNW™ revolves around the efficient distribution of cement particles within the concrete. Incorporating this additive into the concrete mixture significantly reduces the water-cement ratio, leading to improved concrete quality and enhanced strength. Additionally, the set-retarding properties of RNW™ extend the setting time of concrete, allowing for better workability and increased efficiency during the construction process.
One of the key advantages of RNW™ is its versatility. It is suitable for use in various types of concrete, offering benefits such as ease of concreting, improved time management, and enhanced overall efficiency. Furthermore, the composition of this additive is free from chloride and other chemical substances that can potentially cause corrosion of steel reinforcement, ensuring the long-term durability and integrity of the concrete structures.
Choose RNW™ Set Retarding Normal Water Reducing Admixture to elevate the performance of your concrete projects. Experience the exceptional combination of plasticizing, water-reducing, and retarding properties, all while maintaining high standards of quality, durability, and sustainability.
