摘要
混凝土的抗压强度与其测区的回弹值(表面硬度)之间有一定的关系,该关系是以大量的试验数据为依据并考虑其他影响因素,通过回归分析而建立的混凝土回弹值与抗压强度之间的数学表达式。回弹法用于检测混凝土的抗压强度已在我国得到了广泛的应用,实践证明,采用回弹法推定的混凝土抗压强值,对于处理工程质量问题具有十分重要的意义。
There are certain relationship between compressive strength and surface hardness of concrete. Through the regressive analysis of experimental data and other influencing factors con sidered,a relational expression between rebound value and compressive strength of concrete can be established.Therefoe it is a very simple and effective method to estimate concrete compressive strength in situ, and has been used in China commonly.
