Kinetics of the Aqueous‐Phase Copolymerization of AA and HPEG Macromonomer in Acidic Media

Macromolecular Reaction Engineering, Volume 19, Issue 1, February 2025.
A series of aqueous semibatch AA‐HPEG copolymerization experiments are studied in acidic media and the effect of different operation conditions on the kinetics of the copolymerization, and the molar mass are investigated. On the other hand, the accuracy of three different methods for measuring the individual monomer conversions and the HPEG cumulative ...

Improved forecasting of the compressive strength of ultra‐high‐performance concrete (UHPC) via the CatBoost model optimized with different algorithms

Structural Concrete, Volume 26, Issue 1, Page 212-235, February 2025.
Abstract This paper focuses on the applicability of CatBoost models constructed using various optimization techniques for improved forecasting the compressive strength of ultra‐high‐performance concrete (UHPC). Phasor particle swarm optimization (PPSO), dwarf mongoose optimization (DMO), and atom search optimization (ASO), which have been very popular ...

Preparation and properties of retarded cellulose-based polycarboxylic superplasticizers

Journal of Polymer Research
Abstract Cellulose is an important biomass, and the synthesis of chemical products using cellulose is the current hotspot for sustainable economic development. A cellulose-based polycarboxylic acid superplasticizer (CBPCS) was prepared from cellulose hydrolysate, and its properties and mechanism of action were investigated.

Popcorn Effect–inspired Self‐propagating Formation of High‐conductivity Cement Composite for Multifunctional Applications

Advanced Science, Volume 12, Issue 4, January 27, 2025.
This study introduces a novel popcorn‐inspired strategy for self‐propagating expandable graphite‐based conductive cement composites. Through thermal treatment, the graphite expands and forms new conductive networks, significantly reducing electrical resistance by 60%. This enhancement broadens its application scope in electrical applications, including

Internal curing of cement pastes by superabsorbent polymers studied by means of neutron radiography [PDF]

, 2017
Autogenous shrinkage is a problem in cementitious materials with a low water-to-binder ratio. When the internal relative humidity decreases due to the ongoing hydration reaction and selfdesiccation, autogenous shrinkage takes place if no external or ...

Experimental and Machine Learning Analysis of High‐Strength Concrete Incorporating Waste Slag and Recycled Steel Fiber

Advances in Civil Engineering, Volume 2025, Issue 1, 2025.
The synergistic impact of waste slag and recycled steel fiber on high‐strength concrete (HSC) has been needed to produce eco‐friendly concrete in recent times. Consequently, this study aims to investigate the combined effects of waste slag and recycled steel fiber on the fresh, mechanical, and durability properties of HSC. Waste steel fibers (60 mm × 0.
