Abstract
Sustainability is becoming more and more important, which is why the concrete and cement industry are attempting to reduce negative impacts to the environment. One of the methods regarding this is to use industry by-products from the manufacturing of steel products like blast furnace slag (BFS) to replace the raw materials required in cement. The chloride ion penetration has to also be taken into consideration since it reinforces the concrete structure. Thus, the influence of BFS on blocking resistance and chloride ion penetration by using BFS with different Blaine value is studied by using “Standard on Test Methods for Chloride Ion Diffusion Coefficients in Concrete” by electrophoresis (Draft) (JSCE-G571-2003)” and the total chloride ion amount was measured in accordance to JIS R 5202. The result is that using BFS in cement has influences on the penetration properties.
