Normal Water Reducing Admixture

Normal Water Reducing Admixture (NWR™), also known as a superplasticizer, is a widely utilized chemical additive in concrete. Based on Lignosulfonate, this additive serves as both a concrete plasticizer and a water-reducing agent. NWR™ is employed to decrease the mixing water required while maintaining a fixed slump. It enables the production of high-strength concrete by achieving the desired strength with less cement, reducing the need for additional water, or increasing slump without water addition. Applying this admixture improves the hardened properties of concrete, particularly its strength and durability. Additionally, the use of NWR™ allows for the possibility of reducing the cement grade, making it highly suitable for mass concreting and hot air concreting, as it helps reduce the heat of hydration. When incorporated into concrete without modifying the mixing water, these additives act as concrete plasticizers, simplifying compaction operations and proving beneficial for structures with a high reinforcement density.

PRODUCT DESCRIPTION

Normal Water Reducing Admixture (NWR™) is a highly effective chemical additive designed for the concrete industry. This admixture, also known as a water reducer or superplasticizer, is formulated to enhance the performance and workability of concrete mixes.
NWR™ is specifically engineered to reduce the water required in the concrete mix while maintaining a consistent slump. By optimizing water content, NWR™ enables the production of high-strength concrete with improved durability and performance characteristics.
This admixture is based on advanced Lignosulfonate technology, ensuring its compatibility with various cementitious systems. It effectively disperses cement particles within the concrete matrix, promoting better hydration and uniform distribution. The result is enhanced concrete workability, increased strength, and improved resistance to cracking and shrinkage.
NWR™ is a versatile additive that offers several advantages. It allows for achieving higher concrete strengths with reduced cement content, resulting in cost savings and environmental benefits. Additionally, it improves the fluidity and slump of the concrete mix without the need for additional water, simplifying construction operations.
This water-reducing admixture is suitable for a wide range of concrete applications, including structural, architectural, and mass concreting projects. It can be utilized in various weather conditions and is particularly useful when working with challenging aggregate gradations or when concrete placement is difficult.
In summary, Normal Water Reducing Admixture (NWR™) is a reliable and high-performing additive that enhances concrete properties. With its water-reducing capabilities, improved workability, and strength-enhancing properties, NWR™ is an essential tool for achieving superior concrete performance in construction projects of all scales.

    Frequently Asked Questions

    Why are plasticizer additives and water reducers known by this name?

    These additives give concrete the characteristics of fluidity and high efficiency. With this feature, there is no need for a high water-to-cement ratio and we can reduce the water-to-cement ratio. Hence, this valuable product of Afzir Company is a plasticizer and water reducer. They say at the same time.

    What is plasticizer and water reducer made of?

    Concrete plasticizer is a Lignosulfonate-based product obtained from wood pulp sulfite

    How is plasticizer and water reducer added to concrete?

    These types of water reducers, which are known by their own brand in Afzir Company, are added to the mixer when mixing concrete, usually 200 to 650 ml of this plasticizer and reducer are used per 100 kg of cement.
