Ocean Engineering Concrete using High-volume GGBS

摘要：

　　To improve ocean engineering durability,concrete using high-volume ground granulated blast-furnace slag (GGBS) was prepared,its mechanical property and durability were investigated.4% activator and 61% GGBS were used to replace 65% cement in cementitious material.Activator was used to improve workability,volume stability and early strength of high-volume GGBS concrete.Ocean concrete using high-volume GGBS has good impermeability with small gas diffusion coefficient and relative permeability coefficient.As the good property of resistance to chloride-ion penetration with a low effective diffusion coefficient,it can protect steel-bar from corrosions.Property of frost resistance is also favorable.Expansions caused by alkali-silica reaction and sulfate attack fall down markedly after using high-volume GGBS.It is proved that the high-volume GGBS concrete with good mechanical property and durability is applicable to the constructing of ocean engineering concrete.
