Summary: Bleeding is a common problem in concrete slabs, but it can be controlled by adding granite powder or fly ash. Finer particle size distribution, increased specific surface area, and higher bulk density can reduce the amount of water in concrete mix and the bleeding rate. Bleeding can affect the compressive strength of concrete and lead to heterogeneity in physical and mechanical properties across the concrete section. Therefore, proper control of the bleeding process is crucial for achieving homogeneous properties in concrete.

Summary: With the development of urbanization and the economy, the amount of municipal solid waste incineration fly ash has increased. Researchers are paying attention to reducing the leaching concentration of heavy metals in this fly ash and expanding its application in wastewater and biosorption. Non-sintered light-weight aggregates (LWAs) were prepared using MSWI fly ash and coal fly ash as raw materials. The heavy metals in the LWAs were found to be immobilized through encapsulation and adsorption. The leaching rate and cumulative leaching rate of heavy metals were significantly affected by the leaching environment, with a lower rate observed at pH above 1. This research provides theoretical support for using non-sintered and MSWI fly ash-based LWAs in concrete.

Summary: The use of waste fly ash in reactive powder concrete (RPC) can be beneficial to its mechanical properties. Increasing the content of fly ash reduces the flowability of fresh RPC and negatively affects its long-term mechanical properties. Higher curing temperatures improve the mechanical properties, especially in the early stages. RPC with 10% fly ash exhibits the best resistance to salt-freezing. Microscopic observations suggest that fly ash enhances the compactness of the microstructure of RPC, improving its durability. The leaching amounts of toxic metal elements increase with an increase in fly ash content, reaching equilibrium after 5 months.

Summary: Carbonation treatment by alkaline fly ash affects the stability of potentially toxic elements (PTEs), increasing the leachability of PTEs, especially in acetic acid leaching. The formation of carbonate minerals in the ash matrix can decrease the environmental risk level of PTEs, but excessive carbonation can lead to an increase in environmental risk due to decalcification. Both natural and accelerated carbonation increase the potential environmental risk of PTEs in the carbonated fly ash matrix.

Summary: Sulfur and nitrogen oxides (SOX/NOX) emissions from fuel combustion are major air toxic gas pollutants. Existing technologies for reducing SOX/NOX content are costly and require high operating temperatures. This study proposes SiO2/Co(OH)(2) nanocomposites as potential catalysts for SOX/NOX oxidation at lower temperatures using atmospheric oxygen as the oxidant, replacing expensive and hazardous oxidants. The nanocomposites exhibited excellent catalytic properties, suggesting their potential for simultaneous scrubbing of polluting gases in flue gases.

Summary: Ozone pollution is a persistent problem in Spain, and understanding the emissions and trends of Non-Methane Volatile Organic Compounds (NMVOC) is crucial for effective control strategies. A speciated NMVOC emission inventory for Spain from 2010 to 2019 revealed that paint manufacturing, manure management, and domestic solvent use were the main contributors to Ozone formation potential (OFP). The top 10 NMVOC species responsible for OFP were identified, and a reduction in NMVOC emissions and OFP was observed between 2010 and 2019, with a larger decrease driven by paint application industries and the road transport sector. However, an increase in OFP from the public electricity sector is expected by 2030 due to the planned increase in biomass use.

Summary: The particle size distribution (PSD) of emitted mineral dust is dependent on factors such as friction velocity, wind direction, and event type. Dry deposition is identified as a potential cause for the variability in PSD. Dry deposition could represent a large proportion of the emission of both super-coarse particles and smaller particles. The differences in PSDs between regular events and haboob events may be due to differences in dust source fetch and resistance of soil aggregates to fragmentation.
