Water Reducing Admixtures - Sika
Low Range Water Reducing Applications: SikaPlast-500 can be used as an economical low dosage admixture for conventional slump concrete, where water reduction up to 5% is required. SikaPlast-500 shows similar setting properties as a reference concrete. By reducing water SikaPlast-500 improves durability and increases compressive strength.
High Range Water Reducer - Sika
Reduced water cement ratios produce more durable, dense concrete with reduced permeability. Highly effective plasticizer reduces surface defects in concrete elements and improves aesthetic appearance. Sika ViscoCrete-2110 has been formulated to provide maximum water reduction and extended slump retention throughout entire dosage range.
Water Reducers - North America
There are three types of water reducing admixtures for concrete: High-range, mid-range and normal: High-range water reducers provide outstanding engineering performance and or concrete workability. Mid-range water reducers provide excellent concrete workability and finishability.

Both properties increase the clearance intervals and mobility of the cement particles in the cement paste of fresh concrete. This leads to significantly higher water reduction and far greater plasticizing than encountered with conventional superplasticizers or plasticisers based on naphthalene or melamine condensates.
Water Reducing / Plasticizing | EFCA
With a typical dosage of 0.2 – 0.8 % by weight of cement, plasticisers increase the workability at a given water/cement-ratio by between 50 and 100 mm slump with no loss of strength or durability. Alternatively, they can be used to reduce water content in a range of 5 – 12 %. This reduction in water/cement ratio gives significant durability
- How do plasticizers and water reducers affect concrete strength?
- Since the heat of hydration of mass concrete goes down when the cement weight goes down, plasticizers can do this. Plasticizers and water reducers are chemical admixtures used to make concrete more workable. Unless the mixture is “starved” of water, increasing the w/c ratio reduces the concrete’s strength.
- What are plasticizers & water reducers?
- Plasticizers and water reducers are chemical admixtures used to make concrete more workable. Unless the mixture is “starved” of water, increasing the w/c ratio reduces the concrete’s strength. An increase in durability is achieved by decreasing the water content (without “starving” the concrete).
- What is water reducing admixture?
- Water reducing admixture, also known as plasticizer, is designed to enhance the workability of concrete without increasing its water content.
- What is water reducing admixture in concrete?
- Water reducing admixture in concrete is an additive that reduces the amount of water needed while maintaining the workability of the concrete. It can be categorized into two types: ordinary water reducing admixtures and high-performance superplasticizers. Sodium lignosulfonate (SLS) and calcium lignosulfonate (CLS) are examples of ordinary water reducing admixtures.
- What is Kingsun concrete water reducing admixture?
- Kingsun concrete water reducing admixtures are products that reduce the water content in the concrete mixture. By improving the cement-to-water ratio, they enhance strength development, leading to stronger and more durable concrete structures.
- What is the difference between water reducing and superplasticizer?
- Water-reducing plasticizers reduce the amount of water needed in the concrete mix, while superplasticizers can increase the workability of the concrete without increasing the water content. Retarding plasticizers slows down the setting time of the concrete, which can be useful in hot or dry weather conditions.
