Abstract

Concrete structures built in coastal area and used local materials will be affected by environment due to corrosion and deterioration in long time. This study evaluated the effect of salty materials in concrete mixtures (not standard materials) and seawater curing on compressive strength and carbonation. The salty materials contained sea water and coastal sand as replacement of fresh water and river sand and clamshell powder as additional material in concrete mixture. The parameters of evaluation were on compressive strength of concrete cube with 15x15x15cm of dimension and carbonation depth at 56 days which were compared to 28 days. In general, this study found that the use of salty materials in concrete mixture resulted various effects. The use of seawater in mixture increased compressive strength at 28 and 56 days but the use of coastal sand reduced it. The addition of clamshell powder in coastal sand mixture might improve the compressive strength. Curing in seawater reduced compressive strength in line with the age of concrete.
