Abstract


The objective of this research is to investigate the influence brackish water as mixing water on characteristics of mortar
and potential corrosion of reinforcement steel bars. Research was conducted in several stages, firstly, evaluating results
of chloride compound that it was observed in two seasons, dry season and rainy season. Then, data of brackish water
samples were analyzed to predict potential corrosion of steel bars. Secondly, characteristics of fine aggregate and
characteristics of PCC cement paste using brackish water were investigated. Finally, cube mortar specimens were casted
using brackish water as mixing and curing water according with SNI 03-6825-2002 standards. After achievement at
certain day of 3, 7, 14 and 28 days, cube mortar samples were tested in compressive strength. Results concluded that
brackish water improves compressive strength of mortar up to 28 days and the content of chloride in brackish water in
two seasons is not to be potential to cause corrosion of reinforcement steel bars.
