The invention provides an experimental method for corrosion resistance of steel bars for concrete structures in tropical marine atmospheric environment. The method comprises the following steps: Statistics and analysis of climatic and environmental conditions and change rules in coastal areas of Thailand, and establishment of environmental corrosion parameter load spectrum; According to the load spectrum of environmental corrosion parameters, a variety of concrete ratio and concrete thickness were drawn up, different experimental schemes were designed, a set of concrete ratio and concrete thickness were optimized, and the mold was designed according to the size of steel sample and concrete thickness; The reinforced concrete sample is fixed in the mold, the concrete slurry is poured in, the mold is removed after the slurry is solidified, and the reinforced concrete sample is made; The corrosion resistance of reinforced concrete samples was evaluated by analyzing the corrosion kinetics and macro morphology of reinforced concrete samples in different sampling periods. Using this method, the corrosion resistance of steel bars can be evaluated in a short time, and the steel bars with good corrosion resistance can be selected.
