Research of permeability properties of chloride iron in concrete with activated coal gangue powder

ZHOU Shuang-xi(School of Civil Engineering and Architecture,East China Jiaotong University,Nanchang 330013,China)  
The mechanical properties of concrete are enhanced when cement is replaced by 30 percent activated coal gangue powder.The relative chloride penetration coefficient of concrete containing activated coal gangue of 7 days is higher than that of pure concrete.But in the age of 180 days,the relative chloride penetration coefficient of concrete containing activated coal gangue is less than half of that of pure concrete.The property of resistant to ocean water of concrete with activated coal gangue powder is inferior to that of concrete without any mineral additives.The strengths of concrete containing amount of activated coal gangue power and fly ash or slag will enhance when it immerged in the ocean water in 180 d.
