Abstract：Depending on the data at home and abroad of studies on durability of marine concrete, flyash is used to replace sand in concrete so as to improve durability of the concrete in tidal zone. In thispaper, the mechanical properties, durability of the plain high-strength concrete(series Ⅰ), sand-re-placed concrete (series Ⅱ) and cement-replaced concrete (series Ⅲ) by minerals were measured andanalysed. The results show that, the resistance to sulfate attack, steel corrosion, permeation of con-crete with mineral admixtures is superior to that of plain concrete.
