- Abstract
- Development of environment-friendly building materials has recently been increasing with the use of industrial waste and by-products, but concrete containing blast furnace slag (BFS) is excellent in terms of environmental load and shows relatively insufficient early strength. Development of by-products to supplement this insufficiency is deemed necessary. Therefore in this study, an early strength activator blast furnace slag (A-BFS) was developed and environment performance of the developed A-BFS was assessed to assess environmental load (CO2). As a result, early strength was developed in mortar specimen mixed with A-BFS. When environmental load (CO2) was assessed on the mortar specimen, life cycle CO2 emission from production of 1kg of A-BFS was found to be 0.057kg-CO2/kg. © (2014) Trans Tech Publications, Switzerland.
