1. Enhancement of Workability One of the main advantages of incorporating sodium thiocyanate in concrete mixtures is its ability to improve workability. This property is crucial during the mixing and placement phases, as it allows for easier handling and better flow of the concrete. Improved workability can lead to enhanced compaction and reduced formation of air pockets, ultimately resulting in a denser and stronger final product.
Cyanide can enter wastewater through various pathways, predominantly from mining activities where it is used to extract gold and other precious metals. Additionally, electroplating industries use cyanide solutions for surface treatment. Other lesser-known sources include the production of textiles, plastics, and agricultural chemicals, where cyanide compounds are utilized. Given its high toxicity, the presence of cyanide in wastewater must be controlled and treated before discharge into the environment.
