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.
Superplasticizers
Concrete Additives Superplasticizers High-level water reduction products can be used in high strength concrete, pumpability, self-consolidating concrete, low permeability, low water absorption concrete and low shrinkage application.

Sikament S1 | Mid Range Water Reducers
Sikament -S1 is highly effective dual action liquid super plasticizer for the production of free flowing concrete or as a substantial water-reducing agent for promoting high early and ultimate strengths. Workability is greatly improved. Increased place components with densely packed. reinforcement.
Use of Water Reducers, Retarders, and Superplasticizer
There are four types of superplasticizers: sulfonated melamine, sulfonated naphthalene, modified lignosulfonates and a combination of high dosages of water reducing and accelerating admixtures. Commonly used are melamine based and naphthalene based superplasticizers.
- What is a superplasticizer in concrete?
- Superplasticizers permit 30% or more reductions in water content. It is chemical mixings that are added to the concrete to develop its flowing capacity, they assist to minimise the quantity of water in the concrete and enhancing the durability and strength of concrete.
- Which superplasticizer is best for precast concrete?
- In this way, the water content can be reduced without affecting the material's usability. Sulfonated melamine formaldehyde condensates are normally preferred superplasticizers within the precast concrete domain because they do not diffuse the cement setting. Sulphonated Naphthalene Formaldehyde is a high scale water reducer superplasticizer.
- Can superplasticizer improve concrete compressive strength?
- There are so many materials that can be used in concrete mixture to improve compressive strength. This study was conducted by using superplasticizer and reducing water amount in concrete mixture and aimed to find out how big it’s effects on the produced concrete compressive strength.
- How many liters of superplasticizers per cubic meter of concrete?
- Typical dosage of superplasticizers used for increasing the workability of concrete ranges from 1 to 3 liters per cubic meter of concrete where liquid superplasticizers contained about 40 % of active material. In reducing the water cement ratio, higher dosage is used, that is from 5 to 20 liters per cubic meter of concrete.
- What are the benefits of SP additives in concrete?
- Concrete's compressive strength and porosity are both improved by SP additives (Golaszewski and Szwabowski, 2004). This sort of concrete necessitates a large amount of SP additives. Water usage can be lowered by 20% to 40% while still maintaining workability thanks to SP. One of the most significant SPs is polycarboxylate (PC).
- What is the dosage of superplasticizer for self compacted concrete?
- The three dosage (1.0%,1.5% and 2.5%) comply with requirement for production of SCC while 0.5% and 3.0% don’t comply with specification requirement .Dosage of superplasticizer need to produce self compacted concrete range between (1.0%-2.5%) L/100 kg of cement according to the condition and material used in this paper
