Abstract

Cooling Tower buildings are examples of construction that is directly exposed to adverse weather conditions that cause concrete damage in the form of carbonation. damage such as concrete cover spalling, cracks on the surface of concrete walls, and corrosion of reinforcement, Conditions like this need to be handled seriously because they have an impact on the structural safety factor of the building. This study aims to determine the effect of carbonation on the concrete structure of the Geothermal Power Plant Cooling Tower Building on Mount Salak which has experienced degradation of concrete quality due to carbonation. Concrete Analysis method to determine the relationship of the effect of carbonation on concrete strength in the Cooling Tower structure uses Monte Carlo simulation method based on measurements of concrete cover and carbonation depth. Monte Carlo simulation results to estimate the carbonation rate of concrete showed an average of 2.4 cm per year for a simulation period of 25 years. The average carbonation of concrete obtained from probability is 2.28. By repeating the simulation, an average value close to the estimate will be obtained from the coefficient of determination test results of 48.1%. The effect exerted by concrete quality on concrete carbonation is negative, meaning that better concrete quality will reduce concrete carbonation.
