Freeze–Thaw Cycle Durability and Mechanism Analysis of Zeolite Powder-Modified Recycled Concrete

Materials, Год журнала: 2024, Номер 17(11), С. 2671 - 2671

Опубликована: Июнь 1, 2024

The inferior mechanical performance and freeze–thaw (FT) resistance of recycled concrete are mostly due to the significant water absorption porosity coarse particles. In this study, different dosages zeolite powder were used in concrete. A series macroscopic tests evaluate workability FT durability powder-modified (ZPRC). X-ray diffraction (XRD) scanning electron microscopy (SEM) reveal micro-mechanisms ZPRC. results show that increase content leads a decrease slump Additionally, ZPRC with 10% has superior characteristics tolerance conditions. higher strength can be attributed particle-filling effect, storage function, pozzolanic reaction powder, which denser microstructure. effect promotes reduction surface pores aggregates (RCAs). function provide for secondary hydration cement particles while reducing free also promote generation hydrated calcium silicate anorthite, thereby making microstructure more compact. These theoretical guidance engineering application cold regions.

Chitosan/Perlite System as a Microbial Carrier in Anaerobic Digestion of Food Waste: Characteristics and Impact of the Additive Materials

Опубликована: Июнь 12, 2024

The article aims to present the results of research on anaerobic digestion (AD) waste wafers (WF - control) and co-substrate system cheese (WFC control), combined with digested sewage sludge. aim study was evaluate physicochemical parameters chitosan/perlite (Ch/P; 3:1) carrier material verify its effect directions change bacterial microbiome, removal kinetics organic matter AD process efficiency. experiment conducted in a laboratory, periodical mode operation bioreactors, under mesophilic conditions. analyses morphological-dispersive, spectroscopic, adsorption, thermal microbiological properties confirmed that tested can be an excellent option implement biotechnological processes, especially digestion. microstructural were influenced by both components: perlite determined development specific surface area, while chitosan shaped porosity system. less heat-resistant component, threefold higher weight proportion, i.e. chitosan. evaluation quantitative qualitative changes genetic diversity communities, carried out using Next Generation Sequencing (NGS), showed has modifying microbiome. Amount bacteria from phyla Actinobacteria, Bacteroidetes, Campilobacterota, Chloroflexi, Euryarchaeota, Planctomycetes, Proteobacteria decreased Firmicutes, Synergistetes, Thermotogae increased during course experiment. shapes FT-IR spectra indicated dependence degradation rate presence cosubstrate Monitoring measuring key for stability process: pH, VFA VFA/TA ratio (volatile fatty acids/total alkalinity). As result, increase volume biogas/methane produced, influence carrier, recorded WF-control 12.05% WFC-control 19.16%. methane 351.72 m3 Mg-1 VS 411.14 VS, sample it 476.84 518.08 confirming validity combining respective microbial bioreactor.
