Abstract

A study to improve the utilization of waste material as concrete construction material and the durability of concrete was carried out using a Ground Granulated Blast Furnace Slag (GGBFS) material which is the residual material produced by a blast furnace process. This experimental study using 6 normal concrete blocks and GGBFS modified concrete blocks 15x15x75cm sized. Acceleration for corrosion by soaking using seawater that has been modified with the wet dry treatment and addition of 30mg/L NaCl solution. In this study flexural strength testing and corrosion area testing are used. The stiffness of the immersed specimen is smaller than that of the non-immersed specimen. At the time of immersion, concrete with GGBFS has greater stiffness value than normal concrete. The increase in corrosion is seen in the average potential difference that occurs in normal concrete with immersion, namely being 3.57 times and in GGBFS concrete by 2.57 times. The increase in normal concrete corrosion was also seen in the corroded area, namely 5% to 50% active corroded steel, up from 0.52% to 46.88% and 50% to 95% active corroded steel from 0% to 3.12%. It was different with what happened to 40% GGBFS concrete, the active corroded area only increased from 1.04% to 6.43%. The purpose of this study is for better effectiveness concrete in seawater, so it can become one of the alternative solutions for infrastructure development especially for seawater infrastructure in Indonesia.
