Exposure conditions for concrete according to British Standard 8110


Similarly to other international standards, the British Standard 8110-1 defines different exposure conditions based on the design environment. The environment can be: – Mild; – Moderate; – Severe; – Very severe; – Most severe; – Abrasive.   The mild environment is defined as: “Concrete surfaces protected against weather or aggressive conditions” The moderate environment is […]

Design for durability, part I – surface of members in contact with the ground


Similarly to European Codes, the Australian Standards specify the durability requirements according to the exposure classifications. In the following, the requirements for the surface of members in contact with the ground. Members protected by a damp-proof membrane; Exposure classification = A1; Minimum concrete strength, f’c = 20 MPa; Minimum initial curing = continuously for at least […]
