SikaPlast-2004 NS | Superplasticizers
Advantages. SikaPlast-2004 NS is a powerful superplasticiser based on advanced technology which gives the following advantages: Strong water reduction, resulting in high density, high strength and reduced permeability. Less sensitive against variations in aggregates and / or different cement types. High efficiency even at low dosage rates.
Concrete Superplasticizer - High Range Water Reducer in Kingsun
The superplasticizer for concrete has the functions of high-efficiency water reduction, retardation, slump retention and reinforcement. This product has strong adaptability to cement, less dosage, and is easy to use. It is especially suitable for concrete projects that require high-efficiency water reduction and retardation.
Polycarboxylate Superplasticizer Powder & Liquid for Concrete
The water reduction rate of polycarboxylate admixture can reach more than 25% ~ 40%, which is suitable for high-performance concrete production. The loss is small while the slump is light. In the case of ready-mixed concrete for about 2 hours, the slump loss will be controlled within 15% by the application of it, which is beneficial to pumping
Mix Design With Superplasticizers - Civil Engineering Portal
The Superplasticizers are broadly classified into four groups: sulfonated melamine formaldehyde condensate (SMF), sulphonated naphthalene formaldehyde condensate (SNF), modified lignosulphonate (MLS) and others including sulphonic acid ester, polyacrylates, polystryrene sulphonates, etc.
- What is a superplasticizer admixture?
- Superplasticizers are water-reducing admixtures used in concrete production to reduce the need for more than 30% of water. They operate at a certain percentage level. One of their main purposes is to prevent concrete from setting too quickly.
- Do superplasticizer admixtures affect optimum dosage?
- The development of new superplasticizers during the last decades has determined the most important progress in the field of concrete structures. Hence, an experimental investigation was conducted to determine the optimum dosage for the admixtures and to study the effect of over dosage of the mentioned admixtures.
- What is polycarboxylate superplasticizer (PCE)?
- Polycarboxylate superplasticizer (PCE), also known as polycarboxylate ether superplasticizer, is a new generation of high-performance concrete admixture.
- What is a polycarboxylate ether superplasticizer?
- The polycarboxylate ether superplasticizer is an additive commonly used in concrete engineering and has a wide range of applications. The PCE based admixture can significantly reduce the amount of cement and improve the fluidity and pumpability of concrete while ensuring the strength and durability of concrete.
- Can polycarboxylate based superplasticizer improve the crack resistance of concrete?
- The polycarboxylate based superplasticizer can improve the crack resistance of concrete. After adding an appropriate amount of water reducing agent in concrete, the internal structure of the concrete can be improved and the contraction and cracking of concrete can be reduced.
- What are the advantages of polycarboxylate based superplasticizer?
- Low dosage and high water reduction rate. The water reduction rate of polycarboxylate based superplasticizer can be as high as 45%, which can be used to prepare high-strength and high-performance concrete. Small loss when slump is light.
