Attention is increasingly being paid to the technological innovation and development of steel slag. Aiming at the development of environmentally friendly steel slag concrete materials and their use in a recyclable economy ,Baosteel has recently been conducting research on and using many new building materials, including steel slag powder concrete, steel slag pervious concrete, steel slag counter weight concrete and so on. In this way, steel slag has been turned from a kind of solid waste into a value-added material. The technology of steel slag utilization has been enriched and developed,while a new model of using Baosteel steel slag in a recyclable economy has also been explored and practised.展开更多

It combines both resistive and reflective insulating principle. It is composed with many layers of reflective aluminum foils and honeycomb-structure air cells with polyethylene foam. This paper introduces recent South Korean building insulation code and the applications of Low-Emissivity Hybrid Insulation to meet the code.展开更多
