AB  - Portland cement tends to exhibit negative environmental impacts; thus, it is 
      required to find measures that will improve its green credentials. In this study, 
      we report a blended Portland slag cement as an alternative 
      environmentally-friendly building material in order to reduce the total carbon 
      footprint resulted from the production of the ordinary Portland cement (OPC), 
      which may resolve the environmental issues associated with carbon dioxide 
      emissions. The ordinary Portland cement type I enhanced by basic oxygen 
      steelmaking slag (BOF) is produced and casted into cubic and beam-like samples 
      for the compressive and three-point bending tests, and the compressive and 
      flexural strengths are experimentally measured. Numerical simulations are 
      conducted to compare with the experimental result and satisfactory agreements are 
      obtained. X-ray diffraction (XRD) investigations and porosity tests are then 
      carried out using the semi-adiabatic calorimetry, which indicates that 5% BOF is 
      the optimal ratio to accelerate the hydration process while increasing the amount 
      of hydration products, especially at the early curing age of 3 days. Scanning 
      electron microscope (SEM) images further indicate that BOF can be used to prevent 
      the development of microcracks while mitigating their propagation within cement 
      mortar. Our study indicates that the compressive strength of OPC can be 
      critically increased by BOF at the relatively low concentrations of 5%. The 
      blended slag cement reported in this paper provides advanced understanding on the 
      green building material that uses byproduct wastes for the mechanical and 
      electrical performance.
