Cement & Plastic Fillers. 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.
Superplasticizer
Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent. Plasticizers and superplasticizers retard the curing of concrete. [1]
Plasticizer
Plasticizers are also often used when pozzolanic ash is added to concrete to improve strength. This method of mix proportioning is especially popular when producing high-strength concrete and fiber-reinforced concrete. Adding 1-2% plasticizer per unit weight of cement is usually sufficient.
Plasticizers For Concrete - Principle, Types & Advantages - PRODYOGI
Plasticizers are admixtures that are added to concrete to increase the fluidity or workability of a cement paste or concrete. It is also called as workability aids, that are added to fresh or early stage concrete to change its workability characteristics.

Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow a 30% or more reduction in water content. It is chemical admixtures that are added to the concrete to improve their flowing ability, they help to reduce the amount of water in the concrete and to improve the strength and durability of concretes.
- 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.
- 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 is a plasticizer used for?
- Plasticizers are commonly used with polyvinyl chloride (PVC) and concretes. Plasticizers serve several crucial purposes in civil engineering materials: Workability – Plasticizers allow concrete to flow more easily into molds and around rebar during pouring. They make the concrete more malleable and improve slump. This makes large pours easier.
- Which plasticizer is best for concrete?
- Polycarboxylate ether (PCE) – PCEs are high range water reducers that provide increased early and late strength. They allow low water-cement ratios. Sulfonated vinyl copolymers – These versatile plasticizers work well across different types of concrete mixes and temperature conditions.
- How do plasticizers work?
- Plasticizers allow concrete to be poured and molded more easily during construction while reducing cracking as it cures. They also improve the tensile strength of concrete. Plasticizers work by embedding themselves between chains of polymers, spacing them apart. This helps the concrete and plastics become more flexible and malleable.
- 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.
