Researchers of Kim Hyong Jik University of Education have recently developed a non-calcination method of producing tiles to be used at salt works with industrial waste.
In general, those tiles are produced by the calcination method as they should not be eroded by salt water but have high compression strength.
The researchers provided a scientific and technical guarantee for producing them by applying a non-calcination method of adding additives to the industrial waste containing an iron element from iron and steel works.
They have such advantages as long life span, cost-effectiveness and no environmental pollution caused by the discharge of carbon monoxide as coal and other fuel are not used in production.
The tiles with high economic effectiveness have been introduced into several salt works.
