An experimental study on the early compressive strength improvement of cement mortar mixing Ground Granulated Blast Furnace Slag using Industrial byproducts developed in Mock-up rotary kiln

In this study Industrial byproducts that contain large amounts of SiO2 and Al2O3 was fired using mock-up rotary kiln in order to improve early strength of concrete mixing Ground Granulated blast furnace slag. And then 7% of blast furnace slag in the compressive strength was conducted. As a result of confirming compressive strength and activity factor according to the addition Ratio, strength development is worse than using OPC 100%. But when using firing powder, the expectation of increasing strength by curing time was affirmative
