混凝土强度快速测定法一般可分为两类。一类是对已固化的混凝土进行快速强度测定;另一类是对未凝混凝土进行水和水泥含量的测定,根据测得的灰水比来预报混凝土28天潜在强度的方法,这种方法仅仅需要几十分钟左右的时间就能得出结果,并且具有一定的精度,因而也是一种很有发展前途的方法。本文主要介绍后一类方法。国外在对未凝混凝土分析方面进展较快,尤其是日本和美国,这些国家在七十年代发展了较多的研究文章。日本混凝土学会
Rapid determination of concrete strength can generally be divided into two categories. One is the rapid strength measurement of solidified concrete; the other is the determination of the water and cement content of unconsolidated concrete, and the method of predicting the 28-day potential strength of concrete based on the measured gray-water ratio. This method is only It takes a few tens of minutes or so to produce results and has a certain degree of accuracy. It is therefore a very promising method. This article mainly introduces the latter method. Foreign countries have made rapid progress in the analysis of unconsolidated concrete, especially Japan and the United States. These countries have developed more research articles in the 1970s. Japan Concrete Society
