FBECR. THE NEED FOR CORRECT SPECIFICATION AND QUALITY CONTROL

The protection of the reinforcing bars in concrete subjected to hostile environments is discussed in the light of current problems experienced in America and the UK. The repair and maintenance of deteriorating structures built with uncoated reinforcement is becoming more and more costly. The use of Fusion Bonded Epoxy Coated Reinforcement (FBECR), together with current American, Japanese and draft British Standards is examined, and compared with British Gas engineering pipeline epoxy coating standards. Examples are given to illustrate the effect of poor quality control and loose specification. Surface preparation and different methods of application are the most significant factors in the specifications. British Gas and the Japanese specifications are the most satisfactory in this area. Methods of checking the effectiveness of the coating are discussed for electrostatic spraying, tribostatic spraying and fluidised bed dipping. Quality control and quality assurance should cover certification of product conformity as well as quality management systems for all types of reinforcement bar and include the ability to trace production back to the source. Minimum quality control requirements are listed.
