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. In CPI issue 4-2008 the treatment of imperfections of hollow core slabs were already discussed, followed by issue 5-2008, reporting about the treatment of imperfections for precast beams. Issue 6-2008 was showing the treatment of imperfections of precast columns. Issue 1-2009 of CPI dealt with the treatment of imperfections of precast panels. Issue 2-2009 proposed possible treatments of imperfections for precast double tee units, and in this last part of the series, the treatment of imperfections of solid planks, beams and blocks will be discussed. The complete report, published in English, is available at the fib in Lausanne.
