Trade Journals for the Concrete Industry

The global trend towards sustainable construction is be- coming increasingly important and at the same time creates the biggest challenges for the construction industry in relation to CO2 reduction. Low-clinker cements offer the most significant potential to reduce the CO2 footprint of concrete. With the recent release of the new European Standard EN 197-5, which introduces the new cement types CEM II/C M and CEM VI, the construction industry is experiencing significant pressure to adapt its processes to this new framework: These new cements contain less clinker, higher amounts of limestone and supplementary cementitious materials (SCMs) which affect the concrete performance, particularly in relation to workability retention and strength development.
