The Influence of Blast Furnace Slag Content on Durability of High Performance Concrete
This paper reports an experimental study of the influence of finely ground-granulated blast-furnace slag (GGBS) used as partial substitute for Portland cement (PC) on the mechanical properties and durability of high performance concretes. The analysis of the experimental results on concrete at 17.5% content of blast furnace slag with a fineness modulus of 8500 cm2/g, in a chloride environment, showed that it contributes positively to the perfection of its mechanical characteristics, its durability with respect to water absorption and migration of chloride ions. On the basis of the experiments performed, it can be concluded that the GGBS is suitable for formulation of high performance concretes (HPC) and their properties are significantly better compared to the reference concrete (RC).
