Effect of polycarboxylate ether-based superplasticizer dosage
This superplasticizer was added to the mix to make concrete of grade M60 by weight of cement with 0.15%, 0.25%, 0.35%, 0.45%, and 0.55% without altering the w/c ratio. Experimental results reveal that the restricted dosage of the superplasticizer provided in Plain and reinforced concrete code of practice in Indian standard, IS456:2000

polycarboxylate superplasticizer with high water retention. The performance test results show that the product has high water-reducing ratio and better workability when applied to concrete, which can effectively retain the moisture in concrete and ensure the stability of concrete fluidity. 1. Introduction
The Effect of Various Superplasticizers on Ultra High
Four different types of superplasticizers were used; two different PCE based superplasticizers from a leading manufacturer (PCE Name Brand 1, PCE Name Brand 2), one PNS superplasticizer, and one PCE superplasticizer (PCE Local Provider), both of which were provided by a local chemical provider.

- What is polycarboxylate superplasticizer (PCE)?
- Polycarboxylate Superplasticizer (PCE) represents the latest innovation in concrete admixture technology. Unlike traditional superplasticizers, PCE offers unparalleled control over concrete's rheological properties, making it essential in the production of high-performance concrete.
- How are polycarboxylate superplasticizers synthesized?
- In this work, a series of polycarboxylate superplasticizers (PCEs) were synthesized via copolymerization using a novel macromonomer, ethylene–glycol monovinyl polyethylene glycol (EPEG). The molecular structures were modified by varying the side chain length, carboxylate density and integrating sulfonic group.
- Are polycarboxylate-based superplasticizers effective?
- Their effectiveness is determined by their interactions between the individual constituents, which include a variety of fine powders. In this research, different investigative methods were employed to study the influence of polycarboxylate-based superplasticizers (PCs) on the performance of UHPC.
- Does polycarboxylate based superplasticizer make high-performance concrete (HPC)?
- Nowadays, polycarboxylate-based (PCA) superplasticizer (SP) has become the basic ingredient to prepare high-performance concrete (HPC). PCA SP with carboxylic sulfonic groups and long poly (ethylene oxide) side chain was prepared. The behaviors and economies of PCA SP-blended concrete were investigated.
- Do Polycarboxylate ether/ester superplasticizers affect concrete performance?
- Polycarboxylate ether/ester (PCE) superplasticizers are widely used due to their molecular structural designability, low dosage and high efficiency. However, their high sensitivity and strong interactions with clays in concrete reduce their dispersion and water-reduction capability, which can affect the performance of concrete seriously.
- Are shrinkage-reducing polycarboxylate superplasticizers effective in cementitious materials?
- Further, there have been many studies on the performance of shrinkage-reducing polycarboxylate superplasticizers (SR-PCA) in cementitious materials, which are designed by the modified molecular structure of PCs , .
