Making good defects on precast fair-facedconcrete components

concrete and reinforced-concrete surfaces. If such irregularities considered to be defects should occur [see 1, 2], a decision has to be made as to whether and, if so, how these can be repaired. The following article suggests various possibilities for the repair of such defects on young fair-faced precast concrete components. The methods can be equally applied to older fair-faced concretes surfaces and to in-situ concrete, see e.g. [3, 4].
