CORROSION PROTECTION IN PREFABRICATED ELEMENTS OF LIGHTWEIGHT AGGREGATE CONCRETE WITH OPEN STRUCTURE Per Goltermann,

By 

Abstract

The current Danish Code-of-Practice for lightweight structures of lightweight concrete elements DS 420 [1] and the future European product standard for precast reinforced components of lightweight aggregate concrete with open structure prEN 1520 [2] allow both verification by testing of the corrosion protection of the structural reinforcement, but differ in their test methods, corrosion classifications and acceptance criteria. The paper describes the results of an investigation and a test program to verify the current corrosion protection systems (cover, density, coating) and to verify the new test methods. The conclusions are that a short-term test method is suitable and corresponds well to experience in practice and that the requirements in prEN 1520 lead to realistic assessments of the corrosion protection
