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.
concrete plasticizers in Indonesia - Primary Info
Plasticizers, also known as Super Plasticizers or high-range water reducers which reduce water content by 12 to 30 percent and can be added to concrete to make high-slump flowing concrete. Super plasticizer (SP) plays a role in decreasing the viscosity of the concrete, without reducing the strength of concrete and help in pemandatan without
Polycarboxylate Superplasticizer (PCE) For Concrete
Polycarboxylate superplasticizer (PCE), also known as polycarboxylate ether superplasticizer, is a new generation of high-performance concrete admixture. It is a water reducing agent with excellent performance that integrates water reduction, slump protection, reinforcement, shrinkage and environmental protection.
Superplasticizer: Types, Advantages & Disadvantages
Superplasticizers (SPs) are also known as high- range water reducers that are additive used in making high strength concrete. 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.
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.
- What is sikacim® concrete admixture?
- Increased watertightness. SikaCim® Concrete Additive is a high range water reducing concrete admixture specially formulated for the precast concrete element industry; to meet the demand of early removal of formwork due to the early strength gain. Enables concrete placing equipment to be used to its full capacity. Effective throughout dosage range.
- What is polycarboxylate superplasticizer (PCE)?
- Polycarboxylate Superplasticizer (PCE) is a water-soluble concrete additive used to reduce water to cement ratio without affecting the workability of the mixture. PCE increases protection from slumping, then increases the slump retention since cement loses workability with time. PCE increases the structure’s strength after construction.
- What is superplasticizer used in pipe jacking method?
- Superplasticizer is used in pipe jacking method. Superplasticizer use is for water cut-off materials or durable and high resistance waterproofing membranes for shield tunneling method. PCE also can be added for mud withdrawal process to reduce viscosity and increase fluidity.
- What is superplasticizer used in gypsum panel & plasterboard process?
- Superplasticizer can be used in the gypsum panel and plasterboard process. In mixing compound phase, a small amount of superplasticizer are used so that the slurry will flow during manufacture, and to reduce the water and hence the drying time. Superplasticizer is used in pipe jacking method.
- How much sikacim ® concrete additive can be used?
- SikaCim® Concrete Additive can be used at the dose rate 0.30 % - 2.0 % by total weight of cementitious material depending on requirements concerning workability and strength. It is recommended that trial mixes be conducted to determine the exact dosage rate required.
- Can sikacim® concrete additive be added to gauging water?
- SikaCim® Concrete Additive can be added to the gauging water prior to its addition to the dry aggregates or separately to the freshly mixed concrete (on the batching plant or on site into the truck mixer) where added to truck mixer on site, further mixing for three to five minutes should be carried out.
