Abstract:The work reported in the paper is planned to investigate the air-void system and the frost resistance of self-compacting concrete with slag fine aggregates, produced in refining process of metals, such as blast furnace slag (BFS) fine aggregates, ferronickel slag (FNS) fine aggregates and copper slag (CUS) fine aggregates, which were standardized in JIS A 5011 (Japanese Industrial Standard) as slag aggregates for concrete, The positive use of these slag fine aggregates is being enhanced from the view point of utilization and recycling of industrial by-products. Test results are summarized as follows: (1) The air-void system of self-compacting concrete with slag fine aggregates varied depending on the type of slag fine aggregates used in this investigation. Especially, self-compacting concrete with BFS fine aggregates showed much larger air-voids. This was due to the entrapment of large air bubbles in the course of the mixing process of concretes. (2) The highly durable concrete to frost action can he produced by making the proper air void system with the spacing factor of not more than 300-um.
