Chemical Admixtures - Cement
Accelerating admixtures are especially useful for modifying the properties of concrete in cold weather. 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.

Concrete Admixtures: Plasticizers, Water Reducers & More - Ozinga
Concrete accelerator is used to speed the setting time of concrete, allowing it to begin to cure earlier than a typical mixture. This can be especially useful for cold weather placements, as the reduced setting and cure times can lower the risk of frost damage. Concrete Plasticizer. Plasticizers increase the workability of concrete mixtures.

- What is the use of plasticizers in concrete?
- The plasticizers for plastics soften the final product increasing its flexibility. Superplasticizers or High Range Water Reducers or Dispersants, are chemical admixtures that can be added to concrete mixtures to improve workability. Strength of concrete is inversely proportional to the amount of water added or water-cement (w/c) ratio.
- 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).
- 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.
- How do Plasticizers make concrete stronger and last longer?
- Plasticizers make concrete stronger and last longer by reducing the amount of water and cement needed to reach a certain level of workability. 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.
- What makes a good plasticizer?
- A good plasticizer makes concrete or mortar flow in a way that is different from how an air-entraining agent does it. But some plasticizers also add air to the material, making it easier to work. A good plasticizer should add 1% to 2% of the air to concrete at most because adding air to concrete makes it less strong.
- What is a hydrophilic plasticizer?
- The primary purpose of hydrophilic plasticizers is to improve the concrete’s plastic and flow properties, as evidenced by their increased wet ability. This plasticizer makes a lot of air get into the concrete mix. It is possible to lower the tension of the water in the solution and make the concrete more flexible.
