Beams, plates, columns, stairs on the template to fight the concrete a few days can be removed
Mold summer can be demolished the next day, winter recommended multi-pack days to ensure strength. Summer to 75% or as long as 7 days or so, the winter may need 20 to 28 days, the intensity of the speed and temperature, humidity are related, and ultimately rely on laboratory data to decide.
The need for 100% strength; plate less than or equal to 2m, 50% strength can be demolished; less than or equal to 8m greater than 2m, 75% strength can be demolished; greater than 8m need 100% strength; cantilever strength must reach 100%
The strength of the demolition can not be calculated according to the day, according to the site with the conditions of conservation test pieces and components to determine the span, the number of days can only reference; beam, arch, shell span less than or equal to 8m, 75% strength can demolition;
