数十年来,人们一直致力于寻求出一种经济可靠的现场非破坏测量混凝土强度的方法。然而,现行的几种仪器均不能令人完全满意,在美国和加拿大很少使用。由于(现行仪器的)强度指示器所表示的数值要经过换算才能得到所测强度,而换算系数差别很大,不得不多次进行测试和调整,以求得混凝土的较准确的强度。

For decades, people have been seeking to find a reliable and non-destructive way to measure concrete strength in the field. However, none of the current instruments are completely satisfactory and are rarely used in the United States and Canada. Since the value indicated by the strength indicator (of the current instrument) is to be converted to obtain the measured intensity, the conversion coefficient varies so much that it has to be tested and adjusted several times to obtain the more accurate strength of the concrete.
