Chemical Admixtures - Cement
Superplasticizers, also known as plasticizers or high-range water reducers (HRWR), reduce water content by 12 to 30 percent and can be added to concrete with a low-to-normal slump and water-cement ratio to make high-slump flowing concrete.

Types of Admixtures for Concrete - Concrete Network
Added at the job site and keep concrete flowable for a short period of time. At some point, the concrete will lose slump quickly. Type G superplasticizers. Can be added either during batching or at the job site. This admixture will delay setting, but cause the concrete to be flowable for a longer period of time which could delay finishing.
Use of Water Reducers, Retarders, and Superplasticizer
The use of WRA is defined as Type A in ASTM C 494. WRA affects mainly the fresh properties of concrete by reducing the amount of water used by 5% to 12% while maintaining a certain level of consistency, measured by the slump as prescribed in ASTM C 143-90. The use of WRA may accelerate or retard the initial setting time of concrete.
- What is a plasticizer in concrete?
- and more resistant to cold. A plasticizer is an additive used in concrete to improve its workability, performance, and durability. Plasticizers are typically added to concrete mixes to make pouring, shaping, and finishing easier. They can also help to increase the strength and reduce the permeability of the hardened concrete.
- 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 are the benefits of using plasticizers on concrete?
- Enhanced Strength: Certain additives, such as silica fume, significantly increase the compressive strength of concrete, making it suitable for high-performance applications. Better Workability: Plasticizers and other workability enhancers make it easier to mix, transport, and place concrete, reducing labor costs and improving finish quality.
- 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 the different types of concrete additives?
- The most common types of additives include: Water Reducers: Lower the water content in the mix while maintaining workability, resulting in stronger and more durable concrete. Plasticizers: Improve the flowability and workability of concrete, making it easier to place, especially in complex forms or heavily reinforced sections.
- Does USG offer concrete plasticizers?
- Builders and project managers count on USG’s selection of concrete plasticizers and cement plasticizers to strengthen their structures. Our concrete plasticizer products reduce the water/cement ratio to achieve better results. View our plasticizer admixture for concrete and other offerings below.
