we are constructing two spans (25+20 m) bridge with 10 nos girder in each span at Motorway.During casting of girders one of the 25 m girder got accidentally overdose of admixture( water reducing sika 529 BA).on the removal of form work of said girder cracks at various locations were observed .laboratory results of concrete cylinders were satisfactory . cracks were repaired with Sikadur®-52 Injection epoxy and girder was stressed successfully.But during the launching operation cracks in that girder appeared at others locations .should it be used or not?
