Admixture Optimization in Concrete Using Superplasticizers
Two types of superplasticizers were used with different dosages of admixture. In the first type, dosages were 0.8 and 1.0% (per weight of cement) and in the second type they were 0.9 and 1.1% (per weight of cement).
Effect of Super-plasticizer Dosages on Fresh State
With the increase in SP dosage, concrete compressive strength at early age reduced however its strength at 28 days increased by adding SP dosage up-to 2%. Workability and setting time were...
Use of Water Reducers, Retarders, and Superplasticizer
Typical dosage of superplasticizers used for increasing the workability of concrete ranges from 1 to 3 liters per cubic meter of concrete where liquid superplasticizers contained about 40 % of active material. In reducing the water cement ratio, higher dosage is used, that is from 5 to 20 liters per cubic meter of concrete.
Superplasticizer - an overview | ScienceDirect Topics
Superplasticizers (SPs) can strongly influence concrete rheology: the admixture of an SP can improve flowability of concrete. Alternatively, at the same flowability requirement, the water/cement (w/c) ratio can be reduced to improve the strength and durability of concrete (Kwan and Fung, 2012 ).
- Does superplasticizer dose affect concrete performance?
- This paper has been made an attempt to study the influence of superplasticizer dose of 400ml, 600ml, 800ml, 1000ml and 1200ml/100 kg of cement on performance of Concrete. The experimental tests for fresh and hardened properties of concrete for three mixes of 30 MPa grade are studied and the results are compared with normal concrete.
- Can superplasticizer dosage predict the compressive strength of self-compacting concrete?
- Independently of the superplasticizer dosage, the found results allow to predict, basing on the measurement of the rheological properties of a self-compacting concrete, its compressive strength. 4. Conclusion
- Does superplasticizer affect rheological and mechanical properties of concrete mixes?
- The concrete mixes contained eight different dosages of superplasticizer. The used rheology measurements are the slump flow, V-funnel, L-box, yield stress and plastic viscosity. The used mechanical tests are the compressive strength. The superplasticizer effect on these rheological and mechanical properties will be studied in more details.
- What is a superplasticizer in concrete?
- A superplasticizer is an admixture properties of a concrete mixture. The use of a and hardened states. In the fresh state, use of a content of concrete. I f the water–cement r atio water is available to lubricate the mix. In the compaction to produce dense concrete. In with the presence of a superplasticizer . Liboment–163 is added.
- Is superplasticizer based concrete good for compressive strength test?
- For hardened concrete’s compressive strength test, we compared the properties of superplasticizer-based concrete with those of concrete without superplasticizer. The superplasticizer led to a significant water reduction but maintained workability. Content may be subject to copyright.
- 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.
