Webbför 2 dagar sedan · The previous literature proved that lead sludge (LS) from glass manufacturing elongated the setting time and reduced the workability and compressive strength as it contains a large amount of organic matter that adsorbs a high amount of water and hinders the hydration process. Webbuses caustic soda also known as lye (sodium hydroxide: NaOH) as an additive to create a highly alkaline environment and thereby sanitises sludge from human waste. It significantly reduces the public and environmental health risks of latrine sludge. Caustic soda is a white, alkaline, odourless material supplied as flakes packed in drums.
