High‑Performance Powdered Defoaming Technology for Cementitious and Gypsum‑Based Systems
1. Introduction Foam formation poses a significant and persistent challenge in the production of cement-based materials, construction formulations, and a wide array of industrial mixtures. In aqueous systems commonly encountered in these applications, the presence of bubbles disrupts critical processes such as mixing and hydration. This interference manifests as numerous defects in the final product, […]
Synthesis Methods of Polycarboxylate Superplasticizers
The design of the molecular structure is the most critical factor in determining the performance of polycarboxylate superplasticizers (PCEs). Key elements such as the nature of the main chain functional groups, the density of grafted side chains, and the length of the side chains all directly influence dispersion efficiency, slump retention, and compatibility with different cement types. By fine-tuning these molecular […]
Limitations and Challenges of Polycarboxylate Superplasticizers
1. Introduction Over the last three decades, superplasticizers—high-range water reducers—have become integral to high-performance concrete technology. Their ability to enhance workability at low water–cement ratios has enabled the production of stronger, more durable, and more sustainable concrete. Initially dominated by sulfonated naphthalene formaldehyde (SNF) and sulfonated melamine formaldehyde (SMF) , the market has shifted significantly toward polycarboxylate ether (PCE) superplasticizers, the […]
