7.1 Introduction. Superplasticizers are polymeric dispersants
- Can superplasticizers be used in Portland cement?
- The dispersing effect of superplasticizers is not limited to portland cement only and hence they may find application in other cemcntitious systems. Although superplasticizers show some remarkable advantages in pro- ducing concrete, there are some limitations associated with their use. Superplasticized concrete shows a high rate of slump loss.
- Are superplasticizers good for concrete?
- These benefits are so important and numerous that superplasticizers have become key ingredients of modern concretes. For example, they can be used to enhance workability without altering the water-to-binder (w/b) ratio that controls concrete durability and strength (see Chapter 11; Gelardi and Flatt, 2016).
- What type of cement is used in a superplasticizer?
- Initial flow of a cement paste with PCEs with increased dosage. CEM A is a standard NPC (left) and CEM B, a high C3A cement (right). Reprinted from Schober and Mäder (2003) with permission from ACI. The critical dosage and efficiency of a superplasticizer are also dependent on the type of cement.
- Can superplasticizers be integral components of high-performance concrete?
- The use of superplasticizers as an integral component of high-performance concrete is the main topic of this book.
- Which admixture is best for a superplasticizer?
- In North America, when the air-voids system properties (spacing factor) are critical, PNS-based admixtures may be preferred. When a concrete producer buys a superplasticizer, it seldom consists of just a pure solution of one of the previously described superplasticizer polymers.
- Can superplasticizers be used in high alumina concrete?
- However, superplasticizers perform poorly when incorporated in high-alumina cement concrete.t1161 Even at the very high dosage rates, the concrete does not achieve “flow” characteristics and reverts back to the original slump in less than 20 minutes (Fig. 62).
