Abstract

Building structures in seashore environment are more exposed to deterioration especially for reinforced concrete (RC) structures. These conditions become a challenge for people that live close to seashore like Belakang Padang Island, Batam, Indonesia as the buildings is exposed to multiple threats. Thus, it is important to investigate the effect and the damage of current environment to the RC structures health of Belakang Padang Island. This research is conducted at fish market building in Belakang Padang Island. Several methods are used to investigate the studied building such as observation, non-destructive test and sample collection. The samples later are analyzed using XRF and SEM. The analysis result shows that damage of the deteriorated building column is severe as the cover of the column is destroyed and reveal the rebar inside. The concrete surface strength is 20 N/mm2 or 20 MPa base on the non-destructive test which is very low for a concrete strength. The XRF and SEM analysis show that the concrete and rebar structure is severely attacked by sea salt ion (e.g., chloride ions). The rebar also changes in the microstructure as its corroded from the chloride ions. Several scenarios can be concluded from the field investigation and chemical analysis. The attack from sea spray aerosols can contribute to the column exterior deterioration. Meanwhile the interior deterioration can be caused from wetting-drying process from the fish seller activity inside the building.
