SikaPlast-398 SF | Super Plasticizers
SikaPlast-398 SF is a 3rd generation polymer based high performance superplasticizer for producing soft consistency concrete. SikaPlast-398 SF meets the requirements of ASTM C494 type D & G. SikaPlast-398 SF conforms to type G when used at 0.8 - 1.0% dosage, depending on cement type used. SikaPlast-398 SF combines different modes of actions.
SikaPlast-2000 P4 | Superplasticizers
SikaPlast -2000 P4 is a third generation low-mid range super plasticizer for concrete and mortar. It meets the requirements for super plasticizers according to ASTM C494 type G. SikaPlast -2000 P4 acts by different mechanisms. Through surface absorption and sterical separation effect on the cement particles, in parallel to the hydration process
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.
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.
Behaviour of Normal Concrete Using Superplasticizer under
Different dosages of superplasticizer were used in different batches of all 95 specimens, and cured under different curing conditions and then tested for compressive and tensile strengths following...
- Which superplasticizer is best for concrete?
- Sulfonated Naphthalene Formaldehyde (SNF) is another widely used superplasticizer, known for its excellent dispersing properties. SNF is particularly effective in reducing the water content in concrete mixes, which enhances the material’s strength and durability.
- What is a superplasticizer?
- Superplasticizer is chemical admixtures added to the concrete to improve their flowing ability also known as high range water reducers.
- Can superplasticizer dosage predict the compressive strength of self-compacting concrete?
- Independently of the superplasticizer dosage, the found results allow to predict, basing on the measurement of the rheological properties of a self-compacting concrete, its compressive strength. 4. Conclusion
- Does superplasticizer affect rheological and mechanical properties of concrete mixes?
- The concrete mixes contained eight different dosages of superplasticizer. The used rheology measurements are the slump flow, V-funnel, L-box, yield stress and plastic viscosity. The used mechanical tests are the compressive strength. The superplasticizer effect on these rheological and mechanical properties will be studied in more details.
- Can superplasticizers improve the flow properties of concrete?
- The ability of superplasticizers to improve the flow properties of concrete is particularly beneficial in complex construction scenarios. For instance, in projects involving intricate formwork or densely reinforced sections, achieving adequate compaction can be challenging.
- Can a superplasticizer be used in a hydraulic system?
- In the case of hardened concrete, the use of superplasticizer will concrete. located. Concrete has been the core material for this hydraulic infrastructure. fluid are considered too expensive. The most widely accepted deposit and much cheaper, are including even water to drink. It is for this nobility of concrete, that most of the hydraulic works
