Freeze Thaw Resistance of Non-ferrous Slag Concrete
https://orcid.org/http://orcid.org/0000-0002-3215-4747
The objective of this work is to study the freeze thaw resistance of supplementary cementitious materials (SCM) based concrete made from non-ferrous slag (NFS) benchmarked with CEM I 52.5 N and CEM III 42.5 B concrete. NFS is synthesized during the production of Cu metal from Cu scraps. The freeze thaw resistance of NFS concrete containing 70% CEM I 52.5 R and 30% NFS (w/b = 0.45) as binder, as well as of CEM I 52.5 N and CEM III 42.5 B concrete was tested following CEN TR 15177 (2006). The analysis was based on a calculation of the relative dynamic elastic modulus determined by ultrasonic measurements and a determination of the water absorption by mass in function of the number of freeze thaw cycles. Furthermore the relative tensile strength loss after 56 cycles was considered and a microstructural analysis was performed. All concrete mixes showed a relative tensile strength after 56 freeze thaw cycles lower than 100% of the initial value, whereas the CEM III 42.5 B concrete showed the highest strength loss of around 15% followed by 11% for NFS concrete. NFS concrete also showed highest water uptake of around 4% whereas CEM I 52.5 N and CEM III 42.5 B concrete showed values of 1.2% and 2.2% respectively.
