Effectiveness of Thermal Stimulation of Superplasticizers on Fresh
Polycarboxylic acid-based superplasticizers are used in various types of concrete work. Wide variations in environmental temperatures are known to affect how well chemical admixtures perform as superplasticizers, influencing the properties of the concrete. However, little has been reported on changes in performance caused by thermal variations.
- 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.
- 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 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.
- Can polyglykol ML 2400 be polymerized?
- Polyglykol ML 2400 is a polyglycol methallyl ether which can be polymerized directly. Another alternative building block for superplasticizers are Clariant’s Polyglycol allyl ethers (Polyglykol A-type C). Like the Polyglykol ML grades these macromonomers can be directly polymerized, preferably to acrylic acid in water.
