NOTE 1 repair mortar or concrete. T

31、he substrates can be supported by form work on two sides (see 5.4) to ensure the required uniform thickness of The layer thickness shall be (20 f 2) mm for repair mortars up to 5 mm maximum particle size and (40 f 4) mm for repair materials with larger maximum particle sizes, unless recommended othe

32、rwise by the manufacturer. All materials shall be conditioned in the standard laboratory climate (5.1) for a period of not less than 24 hours prior to mixing. The repair mortar or concrete is mixed according to the manufacturers instructions. If no particular instructions are given, the maximum wate

33、r content should be applied in the case of CC and PCC. The repair mortar or concrete is applied to the overhead surface of the prepared substrates according to the manufacturers instructions. NOTE 2 If required, the substrates may be pre-wetted and/or a bonding aid used. After application to the req
