studies on compatibility issues of super plasticizers with
Abstract: The behaviour of the high performance concrete in fresh state can be calculated with the flow behaviour of ... a SNF based Super plasticizer. The water - cement ratio is considered are 0
Experimental Investigation on PCE and SNF Type
Optimum dosage of super plasticizer improves the workability of concrete without adding excess water. At a dosage of 0.5% of SNF super plasticizer (Sikament 2002 NS) and 25% water reduction, maximum strength achieved. At 0.6% of PCE super plasticizer (C Flow 175 M) and 25% water reduction all the strength parameters reached peak value.

The use of HPC would lead to an increase in the usage of Microsilica and Super Plasticizers. A new generation Super Plasticizer would be necessitated considering the stringent requirement of high workability, self-compactions and long hauling times and Super Platicizers will have to cater to these new conditions.
- Can SNF be used as a superplasticizer?
- The key advantage of using SNF as a superplasticizer is the possibility of greatly reducing water content in concrete without the undesirable side effects of the severity of retardation or air entrainment.
- Are PCE superplasticizers better than SNF?
- Currently, SNF condensates are the most extensively used superplasticizers. However, PCE superplasticizers are gradually replacing SNF because of their superiority in a number of aspects. For example, the amount of PCEs required to achieve a specific workability is much lower that the amount of SNF.
- Are carboxylate based superplasticizers more effective than SNF-Based super plasticizers?
- The authors reported that the carboxylate-based (PCE, PCS) superplasticizers are more effective than SNF-based superplasticizers. Under the same dosage, carboxylate-based superplasticizers were able to obtain mortars with considerably reduced yield stress point and low workability loss unlike the case with SNF-based superplasticizers.
- Are superplasticizers better than SNFS and lignosulfonates?
- Usually, these superplasticizers show excellent retention of slump and do not delay the gain of concrete strength. The disadvantage of these superplasticizers is the high cost. PCEs are efficient at lower dosages compared to SNFs and lignosulfonates, however, in achieving the same workability.
- Why does SNF Based super plasticizer have high fluidity?
- SNF-based super plasticizer possesses high fluidity due to reduced monomer and increased molecular weight. Retardation of the cement hydration depends on the molecular weight where the higher the molecular weight, higher the retardation [65, 66].
- What are PCE-based superplasticizers?
- The development of superplasticizers is one of the most important breakthroughs that have led to the production of high-performance concrete. PCE-based superplasticizers are the latest generations of superplasticizers, the addition of which to cement paste provides self-compacting concrete with a very low W/C ratio.
