Generally, the test block for formwork removal is based on 3D strength, 7D strength, 14D, 2 1D and 28D. In 3D, there are also small-area floor formwork removal test blocks when the temperature is high. Ordinary houses have basically prepared the same 7-day test block. For plates less than 2M, 50% strength can be removed; For plates less than 2m-8m, 75% of the strength can be removed; 8m above the plate, 100% strength can be dismantled; For beams, 4M is the standard, and 75% of the strength can be removed; For those over 65,438+000%, everything in the cantilever can be removed with 65,438+000% force. If yours is true, the test block with the same conditions will basically exceed 25 degrees, and it will be sent to the pressure in 3.5 -5 days.
