For the design of service life of structural concrete is more than 100 years, chloride ion content
must not exceed 500 mg/L, using steel wire or prestressed concrete of heat-treated steel bar,
chloride ion content must less than 350 mg/L.
Normally, you need consider treating the water for concrete mixing which from underground,
brackish or sea water.
