The value that is returned from a call to a function is the value of that function call. For example, with that function we can set a variable to the value that is returned using the following code (which would set result to 5). var result = num(3,3); The difference between functions and other variables is that the function has to be run in order to determine its value.

Steel slag is a co-product of steelmaking, with remarkable properties. In terms of mineral composition, it is a calcium silicate, which makes it suitable for many applications.Steel Making Co-Product.Slag is a co-product of steelmaking.Once it is cooled, weathered and crushed, it has remarkable properties.teel slag is a calcium silicate which comes from a renewable source, making it the Green mineral alternative to quarried rock such as limestone.
