Re: Removal of formwork for Vertical member

[Subject Prev][Subject Next][Thread Prev][Thread Next]


Removal of formwork can vary depending on your concrete mix design (i.e. concrete strength, cement type, admixtures - accelerators or retarders, etc.), ambient curing temperatures, thickness of members, and member purpose (i.e. loading/support conditions).  A good reference is ACI 347, "Guide to Formwork for Concrete", which recommends that for columns with a normal concrete mix and curing temperatures above 50 degree F you may be able to remove your forms after 12 hours.  You may also need to specify a minimum concrete strength based on field cured specimens.
