Where permanent formwork is incorporated in the structure extra care is required, as full compaction of the concrete cannot be checked after the formwork is removed.
当使用永久模板时，应特别小心，因为移掉模板后，不能够检查出混凝土是否完全压实。
PRINCIPLE This Method describes the procedure for determining the time required for a sample of fresh concrete to achieve full compaction when subjected to a standardized vibratory action.
原则本《方法》确定了在标准振荡作用下，混凝土拌合物样本要达到完全压实状态所需时间的测定程序。
