WebExpanded slag is one of the most important types of light weight aggregates. The blast furnance slag is a by-product of the manufacture of pig iron. The expanded or foamed slag is produced by rapidly quenching blast furnance slag. The quenching of slag can be done by the following two methods: (a) Water jet process. (b) Machine process. http://web.mit.edu/parmstr/Public/NRCan/CanBldgDigests/cbd215_e.html
