Abstract:
The main objective of this research was to investigate the properties of ternary and binary blends incorporating silica fume, metakaolin, and electric arcfurnace steel slag produced in Libya (LSS). The properties investigated include workability, chloride-ion penetration, and compressive strength. The penetration of chloride-ions was studied using the Rapid Chloride Permeability Test Method, in accordance with the procedures prescribed by AASHTO T277-83 [5]. The study also looked at the effect of the amount of pozzolanic content on the observed trends. It was established that ternary and binary mixtures could differ significantly in both their fresh and hardened properties. The ternary blends exhibited some positively complementary properties, which were not observed in the binary mixtures. Significantly, the ternary blends incorporating metakaolin were found to have greater improvement in strength and chloride-ion penetrability compared to those mixtures incorporating the other two pozzolans used.
