Issue of impermeability grade
Thread Content
I don’t know much about civil engineering. Seeking advice on a 100mm thick CF30 impermeable steel fiber concrete surface layer ； How many resistance grades are there, and can any of them meet the P6 resistance requirement? What is the water resistance grade of a 200 mm thick CF30 waterproof steel fiber concrete surface layer?
Is there no one in the civil engineering department? Please help; I can’t find any information online
You can take a look at the content on page 9 of the Technical Specification for Seepage Prevention in Petrochemical Engineering, GBT50934–2013; a thickness of 100 mm is sufficient to meet the requirements of P6

A thickness of 100 mm has no direct relation to the water resistance grade P6; water-resistant concrete requires the addition of additives, and the dosage of these additives varies depending on the desired water resistance grade. The drawings specify CF30 impermeable steel fiber concrete; theoretically, a requirement for the impermeability grade should also be specified, otherwise it is uncertain how many steel fibers should be added.
