The use of Supplementary Cementitious Materials (SCM) as binder in concrete is increasing, mainly driven by the need of the concrete industry to make concrete more environmentally friendly and in particular to meet official requirements for lower CO2 emissions. Here, it is to replace considerable amount of the high emitting Portland cement with low emitting SCM. The fib Model Code for Concrete Structures 2010 (MC2010) covers the use of SCM, but limits the materials and the amount of SCM. The overall motive of fib Task Group 4.6 (TG4.6) is to prepare the basis for an extension of the MC2010 that includes assessment of less known SCM as well as larger replacements.
TG4.6 aims to prepare a state-of-the-art report addressing the items in chapter 5.1 Materials – Concrete in the MC2010. The constitutive relations can be formulated as in, and assessed in relation to compliance with those given in MC2010.
