Investigating the Effects of Fiber Reinforced Concrete on the
The workability in terms of slump value of all concrete mixes was set 80 ± 10 mm; therefore, a dosage of superplasticizer (SP) was added if the desired slump was not achieved. The mix design was based on the 28 days’ target cube compressive strength of 60 MPa.

characteristics and cohesiveness in concrete, Superplasticizer has played an important role in this part. This research examined the effect of superplasticizer on workability and properties of self-compacting concrete (SCC). Three types of superplasticizers Conplast SP 561, Conplast SP 430 and Conplast SP 264 at different percentages (0, 10,
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.
- What is a superplasticizer used for?
- Superplasticizers (SPs), also known as high range water reducers, are additives used for making high strength concrete or to place self-compacting concrete. Plasticizers are chemical compounds enabling the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more.
- What is polycarboxylate superplasticizer (PCE)?
- Polycarboxylate superplasticizer (PCE), the third generation of high-performance superplasticizer, follows the development of ordinary plasticizers and superplasticizers. It significantly reduces water content while enhancing concrete's workability, strength, and durability.
- What are the different types of superplasticizers?
- According to their dispersing functionality and action mode, one distinguishes two classes of superplasticizers: Steric effects: Polycarboxylates - ether (PCE) synthetic polymers bearing lateral chains (third generation).
- What is the difference between a plasticizer and a superplasticizer?
- Plasticizers are chemical compounds enabling the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent. Plasticizers and superplasticizers also retard the setting and hardening of concrete.
