The paper is devoted to the investigation of the concrete corrosion procedure with the effect of the hydrochloric and sulfuric acids. There is the aggressive acid environment in the most industrial buildings of the chemical industry and galvanic shops. Thus investigation of the corrosion procedures in such environments are very important. The article presents the experimental results of the mass loss, the flexural strength and the compressive strength of the concrete specimens, which depends on the effect of the aggressive environments and time. The paper contains as well the results of studying of qualitative concrete composition and microstructure of the concrete. The testing was performed upon the plain concrete and concrete with antirust coating, namely by silicorganical varnish. The efficiency of the antirust coating with the effect of the aggressive acid environment is also defined.
