Abstract

Every aspect of urban development especially in the sector of infrastructure development cannot be separated from concrete materials. Concrete combines several materials or materials consisting of aggregates mixed with water and cement as binders or fillers and additional materials if needed. Innovation of materials as a mixture of concrete by using rice husk ash. Rice husk ash is one of the innovative materials in concrete technology which can substitute cement to reduce the effect of CO2 pollution. In addition, concrete curing is carried out using heat evaporation to get better compressive strength. Heat evaporation is the process of curing concrete using hot steam curing at a predetermined temperature and time. Construction of buildings around the coast causes concrete to be unable to avoid contact with seawater. Seawater contains 3.5% salt that can eat away at the strength and durability of concrete. Therefore, in this study, a durability test of rice husk ash concrete was conducted in a seawater environment. This study used concrete with a quality of 25 MPa made from rice husk ash as a partial substitution of cement, with percentages of 0%, 25%, 30%, 35%, and 40% of the cement weight. Each sample undergoes steam curing at a temperature of 80°C for three hours. The concrete treated with steam show better durability under sea water environment compare to the concrete cured with normal condition.
