What is formwork striking time?
The study reported 4-6.5-day period to satisfy strength requirement for striking formwork for concrete containing up to 70\% ground granulated blast furnace slag. To avoid damage to vertical members due to frost, [14] suggested a minimum strength of 2N/mm2 to be attained for vertical formwork removal.
How many days does it take to cure a slab?
To get the strongest finish out of your new concrete slab for years to come we suggest taking the time to properly cure your new slab for at least 7 days after installation (28 days is ideal).
