Raw materials for superplasticizers
Raw materials for superplasticizers Superplasticizers are used extensively in larger projects where reinforcing steel requires high workability, for precast concrete and on site where the large water reduction capability provides very early strength concrete with improved durability.
Bio-based admixtures - Sika
Polymers, the main component in superplasticizers, are added to concrete to influence properties such as workability, setting time and durability in a favorable way, depending on the desired application. This eco-friendly innovation is in line with one of Sika's stated corporate goals of sustainable product development.

Suitability of commercial superplasticizers for one-part alkali
Alkali-activated materials are a low-CO 2 alternative for Portland cement in construction. However, one major issue in their use is the poor or varying functionality of the currently available commercial superplasticizers. Especially for one-part (‘just add water’) alkali-activated materials, the number of studies is limited.
- What is a superplasticizer used for?
- Superplasticizers are used extensively in larger projects where reinforcing steel requires high workability, for precast concrete and on site where the large water reduction capability provides very early strength concrete with improved durability.
- What is polycarboxylate superplasticizer monomer?
- Polycarboxylate superplasticizer monomer have good water solubility and can dissolve in water and various organic solvents. They are essential raw materials for the production of new-type slump-maintaining polycarboxylate superplasticizers.
- Which polyglycols are used in synthesis of PCE -superplasticizers?
- Clariant is one of the world's leading suppliers of polyglycols used in the synthesis of PCE -superplasticizers (3rd generation superplasticizers). Our Polyglykol M-types meet all requirements for esterification e.g. with methacrylic acid, acrylic acid and pre-polymerized (meth-)acrylates.
- What are the benefits of superplasticizer mother liquids?
- They endow the superplasticizer mother liquids with a diverse range of constructional properties, including high water saving rate, high slump-retention capability, early strength gain, reduction in viscosity, anti-mud, alkali resistance, and frost prevention.
- Is MPEG a polycarboxylate superplasticizer?
- MPEG was one of the early large monomers used in the production of polycarboxylate superplasticizers. Its synthesis requires two steps: esterification and polymerization, making the process relatively complex.
- What are alternative macromonomers for superplasticizers?
- Common alternative macromonomers for superplasticizers are Polyglycol methallyl ethers (Polyglykol ML) which can be directly polymerized in water. Therefore, this synthesis route saves cost and time and reduces complexity as there is no need for the esterification of a methoxy polyglycol before the polymerization process.
