Construction materials are still exposed to corrosion. Slurry is a mixture of dung and urine. The aggressive corrosive constituents in slurry are urea, uric acid, naturally excreted chloride and as well as ammonia or ammonium salts. Corrosion tests show that the tested steel in animal slurry as a corrosive environment is characterized through a continuous corrosion process, which measure may be surface roughness. In practice roughness parameters for every of the research times can be used to determine the size of steel corrosion. Low carbon steel is often used as a construction material for agricultural equipment. One of the most important factors of constructional materials is corrosion resistance, first of all in demanding animal environment. Equipment with carbon steel can be easy built by welding quickly at a low price, but the biggest problem in aggressive environment is corrosion protection. The purpose of this article is to investigate corrosion resistance in different time (48, 96, 144, 192, 240, 288, 336 hours); using weight loss and profile roughness parameters of structural steel in grade S235JR in natural animal slurry at 303 K.
