Applicable scope:
Used to control the construction quality and schedule: to evaluate the influence of concrete transportation, pumping, pouring, compaction and maintenance to cover strength.
Decide the appropriate time to dismantle templates, to add load, and to do the hot and humid maintenance in the construction.
