The effects of pozzolanic binders and polypropylene fibers on durability of SCC to magnesium sulfate attack

► Metakaoline and zeolite have positive effects compared to negative effect of silica fume. ► The least volume expansion occurred in zeolite SCC specimens encountered sulfate environment. ► The least loss of mass was occurred in metakaoline SCC specimens encountered sulfate environment. ► Application of PP fibers reduced the compressive strength loss of specimens. ► Application of PP fibers reduced mass loss of specimens immersed in Mg-sulfate solution.
