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.
- Do superplasticizers affect the properties of concrete?
- The superplasticizers have positive effects on properties of concrete, both in the fresh and hardened states. In the fresh state, superplasticizer normally reduce tendency to bleeding due to the reduction in water/ cement ratio or water content of concrete.
- What is the best superplasticizer for prestressed concrete?
- In addition, aggregates should be cleaned before mixing to wash away the fine particles that stick on the surface of the aggregate. The superplasticizer used in this study is Glenium C380. It is a new superplasticizer, which not only suitable for prestressed concrete, but also for other types of concrete.
- What are the effects of superplasticizer?
- Effects of superplasticizer are obvious, i.e. to produce concrete with a very high workability or concrete with a very high strength. Mechanism of superplasticizer is through giving the cement particles highly negative charge so that they repel each other due to the same electrostatic charge.
- Does superplasticizer reduce slump loss during transport of concrete?
- When observation is done on the content of superplasticizer, increase in dosage of the chemical admixture will decelerate the rate of setting of concrete, the superplasticizer will help to retain the concrete in liquid state for a longer time, and hence, reduce the slump loss during the transportation of concrete to the site.
- How many l/m3 can a superplasticizer be used?
- However, the dosage can be increased to as high as 5- 20 l/m3. Since concentration of superplasticizer is different, any comparison of performance should be made on the basis of the amount of solids, and not on the total mass. Effectiveness of a given dosage of superplasticizer depends on the water/cement ratio.
- Which specimen does not fabricate with a superplasticizer?
- M and M1 specimen is control specimen here that is why it does not fabricate with any superplasticizer. But MS1, MS2, MS3, MS4 and MS5 contains SP (Glenium C380) in a ratio 0.4, 0.6, 0.8, 1.0 and 1.2 consecutively using admixture dosage of 400, 600, 800, 1000 and 1200 ml/100kg of cement.
