Drying shrinkage inhibition effect and mechanism of polyol shrinkagex reducing admixture on the metakaolin-based geopolymer

Journal of Materials Research and Technology
Geopolymers, environmentally friendly materials, face application limitations due to their high drying shrinkage and propensity for cracking. The shrinkage reducing admixture (SRA) has shown promise in mitigating drying shrinkage in cement-based ...

3D Printing Innovations in Polymeric Porous and Patterned Architecture

Advanced Functional Materials, EarlyView.
Polymeric foams occupy a unique structural space between dense solids and open networks, where engineered void fraction governs mechanical compliance, thermal resistance, and mass transport. Additive manufacturing now enables precise spatial control over cellular architecture, unlocking designer foam structures across applications spanning crash ...

Shrinkage of dates (Phoenix dactilyfera L.) during drying

, 2015
In this paper the shrinkage of Dates (Phoenix dactilyfera L.) during drying was observed. Samples were dried in a convective tray dryer under three different conditions (60 degrees C-11.1%RH, 70 degrees C-7.2%RH and 80 degrees C-4.7%RH) and three ...

Influence of Curing Time on the Drying Shrinkage of Concretes with Different Binders and Water-to-Binder Ratios

Advances in Materials Science and Engineering, 2017
Plain cement concrete, ground granulated blast furnace slag (GGBS) concrete, and fly ash concrete were designed. Three wet curing periods were employed, which were 2, 5, and 8 days. The drying shrinkage values of the concretes were measured within 1 year

A Dual‐Functional Electrolyte Additive for Highly Reversible Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
This study introduces tetrabutylammonium bromide (TBAB) as a dual‐function additive for aqueous zinc‐ion batteries. TBAB disrupts the hydrogen‐bond network of water while TBA+ adsorbs on Zn to improve interfacial wettability and regulate Zn2+ flux, resulting in suppressed dendrite growth and parasitic reactions. This synergy extended the lifespan of Zn|

Long-term drying shrinkage of self-compacting concrete: Experimental and analytical investigations

Construction and Building Materials, 2019
The present study investigated long-term drying shrinkage strains of self-compacting concrete (SCCs). For all SCCs mixes, Portland cement was replaced with 0–60% of fly ash (FA), fine and course aggregates were kept constant with 890 kg/m3 and 780 kg/m3,

Modelling the drying shrinkage of porous materials by considering both capillary and adsorption effects

, 2020
This paper presents a poromechanical model for drying of unsaturated porous media valid for a large range of relative humidity. Using the proper laws of thermodynamics, this model is derived and permits to account for different effects that contribute to

Determination of drying kinetics, specific energy consumption, shrinkage, and colour properties of pomegranate arils submitted to microwave and convective drying

Open Agriculture, 2021
In this study, the drying kinetics, effective moisture diffusivity (D eff), specific energy consumption (SEC), colour, and shrinkage (S b) of pomegranate arils were compared when dried by convective (CV) drying and microwave

Pull‐and‐Push Nanotherapeutic Hydrogels: Scavenging Inflammatory Triggers While Driving Tissue Regeneration in Burn Wounds

Advanced Functional Materials, EarlyView.
A nanounit‐assembled hydrogel employing a “pull‐and‐push” strategy simultaneously scavenges pro‐inflammatory cell‐free DNA (cfDNA) and delivers regenerative therapeutics in response to burn‐induced hyperthermia. By repolarizing macrophages and promoting angiogenesis, this multifunctional platform accelerates burn wound healing, offering a blueprint for

Prediction of drying shrinkage of Portland cement paste: influence of shrinkage mechanisms

, 1991
Ultimate drying shrinkage of paste was investigated in terms of the Gibbs-Bangham shrinkage and the capillary stress mechanisms. Shrinkage measurements and nitrogen sorption isotherms were obtained on cement pastes of water-to-cement (W/C) ratios of 0.4 ...
