Abstract Weaving, a pivotal technique in human construction activities since the Neolithic era, remains unattainable modern concrete construction. Here, novel particle‐polymer coalescence strategy is proposed, which involves electrostatic, bridging, coordinating, and hydrogen bonding interactions, to establish balanced particle cohesion, enabling fabrication of stretchable cement slurry. The bending, knotting, coiling, winding, interlacing filaments for structural textiles successfully...
By spraying polystyrene/SiO<sub>2</sub> nanoparticles as a coating skeleton and polydimethylsiloxane hydrophobic interconnection, lasting self-healing superhydrophobic surfaces were fabricated.
Aqueous iron hydrolysis products and chloride complexes influence steel corrosion kinetics dictate the amount type of formed. Here, we compile a thermodynamic database devoted to aqueous species solid oxides as well complexes, aiming describe their speciation solubility within prevailing chemical environment interest for cementitious systems. We compare calculations empirical data on elemental composition pore solutions from It is found that dissolved concentrations in cement can differ...
Drying cement-based materials is a necessary step to characterize the microstructure by microscopy, adsorption, or mercury intrusion.The isopropanol (IPA) exchange method commonly used replace pore solution prior drying, as it reduces capillary pressure and thereby helps preserve of hydrated cementitious materials.However, some physical chemical effects IPA on hydration products have been reported.These cannot be completely avoided, but can reduced shortening duration, in particular for...
Carbonation of cement-based materials may lead to durability problems, so that it is necessary find a way reduce the effect carbonation on concrete durability. This study investigated effects cellulose nanofibrils (CNFs) carbonated materials. Two dosages CNFs were used prepare cement pastes and mortars. Before after accelerated (4 % CO2 concentration 57 relative humidity), their microstructure, mineralogical composition, moisture retention capacity, drying kinetics, water absorption...
Supramolecular polymers can be formed by self-assembly of designed subunits to yield highly ordered materials. In this paper, hierarchically structured materials, from molecules nanofibers macroscopical hydrogel, were fabricated pH-induced assembly C(12)-GAGAGAGY, a peptide amphiphile (PA) based on silk fibroin. Due the different acid dissociation constants carboxyl and phenolic hydroxyl groups tyrosine residue (Y), PAs showed unique pH sensitive aggregation behaviors. It was found that not...
Corrosion products, originating from steel corrosion and precipitating in the concrete pore system, can lead to cracking spalling of cover. Related premature structural repair causes high costs. Thus, reliable quantitative models are needed, which currently do not exist. Here, we present a new conceptual model describe fate ferrous ions that released at surface during process. The key novelty our approach be found explicitly considering kinetics oxidation transport Fe2+ solution. These two...
The development of controlled processes for continuous hydrogen generation from solid-state storage chemicals such as ammonia borane is central to integrating renewable into a clean energy mix. However, date, most reported platforms operate in batch mode, posing challenge controllable release, catalyst reusability, and large-scale operation. To address these issues, we developed flow-through wood-based catalytic microreactors, characterized by inherent natural oriented microchannels....
Superplasticizers are polymeric dispersants that play a major role in concrete technology. Despite their ubiquity and much research on working mechanisms, many questions remain about the effects of molecular structures mechanism, particular ability to lower yield stress particulate suspensions. It is generally recognized superplasticizers decrease attractive interparticle forces, thereby reducing or eliminating stress. also often assumed changes should be proportional forces. This paper...
Abstract Anomalous moisture transport in cement-based materials is often reported the literature, but conventional single-porosity models generally fail to provide accurate simulation results. Previous studies suggested that anomalous could be caused by different velocity large and small pores. Based on this concept, present study proposes a continuous dual-permeability model for material. The proposed includes contribution of both liquid water vapor, which are governed advection vapor...
