Task Group 6.8 of the fib Commission 6 on Prefabrication recently published a State-of-the-art report about the treatment of imperfections in structural precast concrete (fib Bulletin No. 41). Since this is a very important topic for the precast industry, CPI will publish excerpts of this report in a series of 6 publications. The complete report, published in English, is available at the fib in Lausanne.
