A continuous solidification process of blast furnace slag was developed to promote the use air-cooled coarse aggregate for concrete. In this process, molten can solidify in only 120 s and thickness is about 25 mm. This suppresses gas generation greatly reduces water absorption. Most crystalline, part has a glass layer on its surface. Slag with brittle because it contains several cracks. Therefo...

Consideration for environmental load using blast furnace slag in concrete, we conducted various experiments. As results, even if a large amount of slag, satisfy the required performance fresh concrete and structures by conventional mix design. The durability is ensured wet curing period set from average temperature during expression compressive strength. Compared to ordinary Portland cement, ca...

Blast furnace gas is the byproduct of smelting steel production process, and is the important secondary energy source. It is can be used as fuel for engines to generate electricity for most middle and small steel enterprises. In order to understand the combustion mechanism and provide the basis for the design of blast furnace gas engine,premixed laminar combustion experiments of the blast furna...

In order to reduce energy consumption in the blast furnace ironmaking process, it is important promote not only rapid reduction of ore but also carburization and melting metallic iron. this study, use carbon-iron composite which an agglomerate fine iron carbonaceous material was focused on, effects type slag content on were examined.

Ultra-High Performance Concrete (UHPC) improves the bearing capacity as well durability of structural concrete. This study aims to investigate constituents UHPC in both phases: aggregate and cementitious materials. The proper ratio mixture was chosen based on combining an gradation quartz sand crushed stone. In addition, compressive strength hardened cement paste investigated achieve optimal si...
