The paper presents the assumptions of the test method that enables comparative assessment of the resistance of concretes exposed to aggressive environments to be carried out, especially an environment characteristic for sewer conduits. The assumptions of the method, necessary test equipment and reagents have been described. The algorithm of conducting tests of the resistance of concretes to selected aggressive environments, and also the method of determining the resistance, have been discussed. The results of the analysis, after their implementation, can be used to standardize the method of assessing concretes exposed to aggressive environments. This will enable a reliable comparative assessment of the different concretes that are used to especially manufacture precast concrete products for constructing sewer conduits to be carried out.
