AB  - Concrete is a porous material. Chloride ion penetrates into the concrete through capillary pores.
Chloride ion is one of the elements generated corrosion on reinforcement of concrete. To protect reinforced
concrete due to corrosion attack, some methods can be applied in concrete to improve its property.
Hydrophobic additive material, calcium stearate is an additive material increased corrosion attack resistance of
concrete. This study, investigates the effect of calcium stearate on concrete grades 20, 30 and 40 MPa. Calcium
stearate 0, 1, 5 and 10 kg per is added in concrete per cubic meter. Two types of testing which are water
absorption and accelerated corrosion are conducted in the laboratory. Specimen for water absorption is a
cylinder with a diameter of 75 and 150 mm in height. Accelerated corrosion is applied in reinforced concrete
specimen 100×100×200 mm in order to study the reliability calcium stearate as a protective additive from
corrosion. There are thirty six water absorption and accelerated corrosion of concrete specimens. The results
show that the water absorption and the corrosion rate decrease significantly due to the addition of calcium
stearate. Higher content of calcium stearate, the water absorption and corrosion rate are reduced. Furthermore,
when concrete grade increases, the water absorption and corrosion rate in concrete also decline.
