QUOTE(icemanfx @ Sep 14 2020, 03:20 AM) What was the extent of rust? RUST is caused by the reaction of air (O2) and moisture (H2O), and it is a common and natural phenomenon for most steel products. IT SHALL NEVER BE CAUSE OF CONCERN/REJECTION OF REBAR, AS PER BIS. CORROSION is an electrochemical reaction between a metal and its environment.   |

QUOTE(ryan@chua @ Sep 14 2020, 08:58 AM) Boss, that clause apply to normal % of surface rust caused by normal water so is acceptable. Caused by Acidic Rain and keep at site very long is not acceptable and have to send for testing. Wash out the rust of rebar on site is very normal procedure in Singapore and Australia, maybe not in Bolehland, cheers. According to BIS, rust should not be more than 20% which has been tested and certified The concern with rust is how the iron rebar being stored and protected from the elements Washing is common but you know Malaysia anything is possible like you said chong8888 liked this post
