Superplasticizer: Types, Advantages & Disadvantages - Constructionor.Com
Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow a 30% or more reduction in water content. It is chemical admixtures that are added to the concrete to improve their flowing ability, they help to reduce the amount of water in the concrete and to improve the strength and durability of concretes.
- What are the advantages and disadvantages of superplasticizers?
- The advantages of superplasticizers include: (1) production of concrete having high workability for easy placement, and (2) production of high strength concrete with normal workability but with a lower water content.
- Which superplasticizer admixture is better?
- Based on the findings, out of three superplasticizers, PC—based admixture showed a better improvement in strength aspects compared to other mix. Compressive strength of UHPC (a) SNF admixture (b) SMF admixture (c) PC admixture
- Do superplasticizers control workability?
- Therefore, at low w/c and with superplasticizers, it is the effective surface coverage of cement particles by superplasticizers that controls workability (see Section 16.3.1 and Chapter 11 (Gelardi and Flatt, 2016))—something that standard mortar tests are not designed to evaluate.
- What is a superplasticizer used for?
- Superplasticizers are used to increase the fluidity of concrete without adding excess water. These molecules physically separate the cement particles by opposing their attractive forces with steric and/or electrostatic forces, as explained in Chapter 11 (Gelardi and Flatt, 2016). As a result, the concrete is easier to place.
- What are the properties of a superplasticizer?
- The most important property of a superplasticizer is its ability of dispersing the cement particles. Electron microscopic examination reveals that in water suspensions of cement, large irregular agglomerates of cement particles form. By the addition of a superplasticizer, the material is dispersed into small particles.
- When were superplasticizers used?
- In North America they were used from 1974.1’1 The advantages derived by the use of superplasticizers include pro-duction of concrete having high workability for easy placement, and pro- duction of high strength concrete with normal workability but with a lower water content.
