Study on the Synthesis and Performance of Tetra-Copolymer Polycarboxylate Superplasticizer [PDF]

open access: yesE3S Web of Conferences
In this paper, a terra copolymer polycarboxylate superplasticizer (PCE) was synthesized using modified polyether (TPEG), acrylic acid (AA), sodium methallyl sulfonate (SMAS), and diethyl vinylphosphonate (AADE) as the main raw materials, under the action

Influence of PEG Addition on the Reactivity of a Metakaolin‐Based Geopolymer

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 10, October 2026.
PEG induces water redistribution within the activating solution, creating PEG‐rich and silicate‐rich domains that modify the local chemical environment. These interactions influence geopolymerization process and affect the balance between structural stability and flowability.

Polycarboxylate Superplasticizers Used in Concrete: A review

open access: yesInternational Journal of Experimental Research and Review
Modern concrete frequently uses a variety of chemical admixtures, like setting time-retarding admixtures, viscosity-modifying admixtures (VMA), and superplasticizers (SPs). These chemical admixtures greatly impact cement components like film-forming capacity, flowability, and film drying time.

Efficiency of Superplasticizers in Low‐carbon Alkali‐activated Slag–Silica Fume Binders Governed by Polymer Solubility

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT Workability control of alkali‐activated binders (AABs) remains an obstacle to producing low‐carbon clinkerless ultra‐high‐performance concrete, as their formulation usually necessitates low water‐to‐binder (W/B) ratios, high binder content, and concentrated activator solutions. To address this challenge, a greener and more manageable composite

Ettringite Seeds for Strength Enhancement: Novel Synthesis via One‐Step Co‐Precipitation

open access: yesJournal of the American Ceramic Society, Volume 109, Issue 8, August 2026.
ABSTRACT Reduced early strength can be a barrier to the adoption of cements blended with high levels of limestone. Chemical admixtures based on nucleation seeding are emerging as a potential solution. Herein, while synthesis of C‐S‐H‐based seeds has been thoroughly investigated in the literature, there are limited synthesis protocols available on other
