Chloride ions erosion is a negative factor for concrete sustainable usage. Fiber addition potential solution, which promotes tight structure formation resulting in the resistance of chloride ions. Corn straw kind crop waste widely sourced that can be used as reinforcement material. The traditional recycling method corn including burnt ash not environment friendly. This work aims to pre-treat fiber (CSF) by some convenient methods (untreated, water-treated, alkali-treated) and add treated CSFs directly into prepare fiber-reinforced with excellent mechanical properties high ability component content different was tested study fibers composition microstructure change. heat hydration, compressive strength flexural were hydration degree effect on performance. rapid permeability (RCPT) migration (RCM) tests designed reinforced concretes In addition, further explore mechanism performance change, water absorption rate (WAR) mercury intrusion porosity (MIP) provide more supporting information from micro-level. It concluded CSF Na2SiO3 has least impurities rougher surface larger specific area bonding cement substrate. Compared original concrete, WT-CSF NT-CSF increased 15.7%, 17.8%, 33.4% respectively. results RCM RCPT show decreasing trend shows greatest decrease 20.1% 17.5%, Except less CSF, improvement mainly due especially contributes denser based MIP WAR results. viscosity solution acts binder helps tighten between substrate CSF. adsorbed alkaline provided facilitates migration. At same time, cellulose containing many hydroxyl carboxyl groups ion its weak conductivity binding force exchange.

Advancements in natural fiber composites: Innovative chemical surface treatments, characterizaton techniques, environmental sustainability, and wide-ranging applications

Hybrid Advances, Год журнала: 2024, Номер 7, С. 100282 - 100282

Опубликована: Авг. 28, 2024

Natural fiber composites (NFCs) are increasingly recognized as sustainable and environmentally beneficial substitutes for traditional materials. The present study discusses chemical surface treatments that promote the adhesion of natural fibers hydrophobic matrices, resulting in improved mechanical characteristics. review aims to examine different treatments, evaluate their influence on qualities, estimate environmental consequences NFCs using a life cycle assessment (LCA). It includes characteristics, advantages, disadvantages newly discovered like acai, guaruman, corn straw, examines bromodecane, lime, tannic acid, which improves adherence between providing better tensile, flexion, impact intensity. Additionally, it benefits NFCs, stressing lower carbon footprint compared synthetic composites. Critical data reveal while considerably increase NFC performance, treatment choice must be adjusted individual applications combine qualities sustainability. This broadens knowledge provides routes future research build more efficient eco-friendly with spanning construction, automotive, packaging sectors.

Effects of the Moisture Content on the Flow Behavior of Milled Woody Biomass

ACS Sustainable Chemistry & Engineering, Год журнала: 2023, Номер 11(31), С. 11482 - 11489

Опубликована: Июль 28, 2023

Handling milled biomass particles in equipment like hoppers and feeders has been a long-lasting challenge the bioenergy industry because of poor flowability these low density, high aspect ratio, irregularly shaped particles. The inner pores woody complicate granular flow behavior. When water exists intra- inter-particle with sizes ranging from nanometers to micrometers, intricate processes such as hydrogen bonding, capillary effects, liquid bridge, lubrication occur. However, knowledge how alter bulk behavior is severely lacking. This study investigates loblolly pine chips wedge-shaped considering moisture content. fiber saturation point (FSP) material (30%) was determined through differential scanning calorimetry analysis. compressibility shear resistance were found increase increased content meso-scale testing. Moreover, hopper simulations suggest that effective discharge rate decreases by 50% increasing up FSP, beyond which no apparent influence on discharge. highlights importance quantifying FSP understanding at various contents sheds light trouble-free handling wet industry.

The role of flexural particles in the shear flow of pine residue biomass: An experiment-informed DEM simulation study

Powder Technology, Год журнала: 2024, Номер 440, С. 119771 - 119771

Опубликована: Апрель 17, 2024

An experiment-informed discrete particle simulation study was performed to investigate the role of flexural particles in shear flow milled pine residues. Physical anatomical fraction samples were tested an FT4 powder rheometer. A chip model for bark/stem chips and a fiber needles proposed DEM. The simulations show mixed fibers/chips require higher force torque drive than pure or fibers. mass flexibility fibers reveal nonlinear inter-dependency on impacting fibers/chips. Polydisperse well match needle-rich attributes, while polydisperse agree reasonably with bark/stem-rich samples. DEM indicates that flowability residue biomass is determined collectively by various material attributes fractions, which must be considered when developing preprocessing methods conversion-ready adequate handling performance.
