Disposal of steelmaking slags by accelerated carbonation

The possibility of disposal of steelmaking slags by using accelerated carbonation is proposed for consideration in this article. The current state of using of steelmaking slags in construction, and the technology of accelerated carbonation are briefly described. The examples for application of carbonation technology in the production of construction products are considered - the replacement of river sand with mixture of slag and river sand, and also the substitute of commercial cement board with slag board with a sawdust filler; quantitative and qualitative characteristics of both raw materials and final products are given, general conclusions about the efficiency of the technology of accelerated carbonation of steelmaking slags disposal are drawn.
