Behaviour of Normal Concrete Using Superplasticizer under
The highest and lowest values of compressive strength were obtained with the addition of 0.5% and 1% superplasticizer respectively. It was found that without increasing the W/C ratio, the addition...
The effect of superplasticisers on the workability and compressive
Using RA in concrete is an alternative to dumping it and also helps the sustainability of natural aggregates’ reserves. Early research focused mostly on processing concrete waste, its size grading, mechanical characteristics and durability aspects [1], [2].
Effect of Superplasticizer on Fresh and Hardened Properties of Concrete
This paper has been made an attempt to study the influence of superplasticizer dose of 0.6, 0.8, 1.2, 1.8 and 2.5 percentage on performance of concrete. The experimental tests for fresh and...

Effect of the Types of Superplasticizers on the
Superplasticizers (SP) are one of the most important constituents of cement cementitious mix mixes. It makes cementitious mix flowable at a low water-cement ratio without segregation and...
- Do superplasticizers improve the workability of concrete?
- This signifies that the superplasticizers used in this study has not only improved the workability of concrete but has also had a positive impact on the concrete strength in construction industry as a whole, thus more suitable compared to the past studies in consideration. ...
- Which superplasticizer is more effective?
- Especially PCE-based superplasticizers are more effective as their absorption by blended cement particles is often higher. High performance concrete like Self compacting concrete (SCC), high-fluidity concrete and high-performance concrete can be achieved by using advance superplasticizers. 2.
- Does superplasticizer admixture improve workability and compressive strength?
- Results showed that the addition of superplasticizer admixture improved workability and compressive strength. The experiment program included tests on workability, slump test, and flow table.
- 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.
- Does superplasticizer reduce water demand while maintaining workability of blended cement?
- To sum up, the following conclusions can be drawn: 1. It is expected that superplasticizer will lower the water demand while maintaining workability of blended cement. Especially PCE-based superplasticizers are more effective as their absorption by blended cement particles is often higher.
- Can superplasticizer be used with low carbon cement?
- Interaction of superplasticizer with the cementitious mix are presented. Compatibility of commercial superplasticizers with low carbon cement is discussed. Effective use of modified superplasticizer is under-represented in the field of low carbon cements. Ongoing research work on use of superplasticizer and cellulose polymer is presented.
