随着混凝土生产的工业化,对混凝土质量控制提出了更加严格的要求。而传统试验方法远远不能满足生产的需要,迫切需要一种有效的混凝土强度快速测定方法,以便为混凝土生产及时提供可靠的资料。现就国外在这方面的发展与应用概况做一简要介绍。 With the industrialization of concrete production, more stringent requirements have been put on the quality control of concrete. However, traditional test methods are far from meeting the needs of production. There is an urgent need for an effective method for rapid determination of concrete strength in order to provide reliable data for concrete production in a timely manner. This is a brief introduction to the development and application of foreign countries in this area.
