Concrete Plasticizers, Cement & Plastic Fillers | USG
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.
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.
Plasticizers For Concrete - Principle, Types & Advantages
The main advantages of using plasticizers are: Improves workability of concrete without the addition of extra water. Improves the strength of concrete without increasing the cement content. Increase the strength characteristics of the finished concrete foundation by twenty five percent.
Superplasticizer: Types, Advantages & Disadvantages
Superplasticizers are mainly used in pumping concrete, casting heavily reinforced members and precast elements of concrete. Advantages of Superplasticizer: 1. Superplasticizers reduces the water content. 2. It reduces the cement content. 3. Also, increases the workability of concrete. 4. It reduces the permeability of concrete. 5.
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.
- 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 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.
- Do Plasticizers improve concrete workability?
- Reduced likelihood of cracking and increased cold resistance. In conclusion, plasticizers play a crucial role in improving concrete workability, performance, and durability. They offer advantages such as increased strength, ease of shaping, and improved resistance to cracking.
- 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 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.
