Question:

Cast in situ floor and girder formwork can be removed a few days?

10-3 degrees of weather, cast in situ floor and girder formwork can be demolished a few days? 25 days enough? There's a wall on the beam.

Answer:

When the bottom formwork of the reinforced concrete slab with a span of 5m is removed, the concrete strength should be greater than or equal to 75% of the standard value of concrete cube compressive strength.
For the cantilever member of concrete structure engineering, the concrete strength can reach to 100% of the standard value of concrete cube compressive strength.
For the concrete structure engineering, the concrete strength can reach the design of the concrete cube compressive strength of the standard value of a certain amount, before the template can be removed the standard value.
If it is summer side touch about 5-7 days is not a problem, the floor of the bottom mold principle that needs to be kept until the floor block to achieve strong design. After the test block strength test qualified to dismantle the bottom mold testing stations in concrete, but in the bottom die and the support under the premise of more than 7 days can be started in the above line ready on a layer of formwork, about 10 days can start pouring a layer of concrete.
