In the previous research, the authors clarified that blending using fly ash or ground granulated blast-furnace slag as an additive improves salinity permeation resistance compared to blending ordinary plain portland cement. In this report, with the aim of further improving salt resistance performance, special inorganic fine powders expected for high strength and high durability of concrete are used in combination with the preparation of the previous report, and salt penetration resistance is compared and evaluated. As a result, fixation of salt content was promoted by the use of the special inorganic fine powder, the apparent diffusion coefficient of chloride ions was lowered, and the improvement of salt resistance performance by the special inorganic fine powder was recognized.
