Industry response to sustainability challenges

Ian Riley | CEO World Cement Association

Despite the spate of recent positive adverts, progress on industry-wide carbon abatement has stalled since 2012. According to GNR, after dropping 18 % between 1990 and 2012, net CO2 emissions/ton cementitious have remained flat.
In 2018, the WCA held the Global Climate Change Forum, which highlighted initiatives that will make an impact on carbon emissions reductions in the long term including: optimising the use of cement in construction, exploring the potential of innovative technologies, and supporting the transition to a low-carbon built environment.

Investigations into the mechanical properties of Portland slag cement based on GBFS and steel slag
The aim of the study is to investigate the utilization of steel slag in the manufacture of Portland slag cement (PSC) by partial replacement of granulated blast furnace slag (GBFS) with steel slag. In spite of its nonconformity in terms of glass content (≥85 %), as specified in Indian standard IS:12089-1987 for slag to be used in the manufacture of PSC, different PSC blends were prepared using 40, 45, 50 and 55 wt.% of steel slag to investigate the sole use of steel slag in cement.
