form removal 1

[kuntay]

Hi, Would you please inform me about the form removal times of slabs? What must be the compressive strength of concrete (in terms of percentage of design strength) to begin form removal. Thank you in advance

For slabs on grade, removing the side forms within a few hours (in warm weather) is usually not unreasonable. For elevated slabs there are, of course, other considerations. In any event, with or without the forms, the concrete needs to be protected from damage and allowed time to cure properly. Here is a short article with more detailed recommendations
