The differences between soil grouting with cement slurry and cement-water glass slurry
Cement slurry and cement-water glass slurry are the most widely applied for soil grouting reinforcement project. The viscosity change of cement slurry is negligible during grouting period and presumed to be time-independent while the viscosity of cement-water glass slurry increases with time quickly and is presumed to be time-dependent.

ABSTRACT Heavy metals in municipal waste incineration fly ash are potentially harmful to the ecological environment and human health. To mitigate the hazards of fly ash, this study attempts to detoxify fly ash through organic acid washing pretreatment coupled with cement/sodium diethyldithiocarbamate (DDTC) solidification.

ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Metasurface Enhanced Photothermal Cement Foam for Robust and High‐Throughput Seawater Desalination
Schematic of 3D metasurface‐enhanced cement foam for robust and high‐throughput seawater desalination. This study presents a cement‐based solar evaporator (CSE) fabricated in one step via viscoelastic lithography with simple negative pressure. In addition to boosting solar‐to‐vapor conversion efficiency via excellent light‐harvesting capacity, the ...

Characterization of a two‐phase hybrid flotation column
Abstract This study explored the performance of a novel hybrid flotation column, which combines the advantages of a mechanically agitated cell with a flotation column and compared the results with a conventional flotation column setup. The experiments were performed in an air/water two‐phase system under varying airflow rates, frother concentrations ...
