Sika ViscoCrete-20 HE | PCE based Super-plasticizers
Sika ViscoCrete-20 HE is a liquid admixture for concrete and mortar which is used as high range water reducer or superplasticiser. Sika ViscoCrete-20 HE is designed to work on a combination of electrostatic adsorption and steric repulsion effects allowing solid particles to be effectively dispersed. Therefore a high level of fluidity

Suitable for use in tropical and hot climatic conditions. Sika Plastiment PR-450 provides the following properties:
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.
Superplasticizer
Superplasticizers ( SPs ), also known as high range water reducers, are additives used in making high strength concrete. 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.
Selection of Superplasticizers for High-Performance Concrete
The first moment consumption of Superplasticizer molecules after the mixing is qualified as the cement/Superplasticizer compatibility. It is very difficult to make high-performance concrete with a very low water-cement ratio, that it will still have a slump value of 50mm 30 minutes with an initial slump value of 200mm.
- Which superplasticizer is best for precast concrete?
- PANTARHIT® F (FM) is a superplasticizer with accelerating properties suitable for producing ready-mix and precast concrete. PANTARHIT® FT100 (FM) is a high performance superplasticizer for producing high consistency concrete at low water/cement ratios in precast concrete plants.
- What is a superplasticizer used for?
- Superplasticizers (SPs), also known as high range water reducers, are additives used for making high strength concrete or to place self-compacting concrete. Plasticizers are chemical compounds enabling the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more.
- 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.
- 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 polycarboxylate superplasticizer?
- Polycarboxylate superplasticizer (PCE), the third generation of high-performance water reducer (water reducing admixture), follows the development of ordinary plasticizers and superplasticizers. It significantly reduces water content while enhancing concrete's workability, strength, and durability.
- 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).
