Twelve concrete mixtures with different quantities and compositions of supplementary materials were tested.

The inclusion of supplementary cementitious materials in sufficient amounts, such as ground-granulated blast-furnace slag and silica fume, proved to be highly effective in improving the durability properties of the concrete.
