使用无损、实时、可靠和廉价的技术来现场评估混凝土结构的抗压强度是建筑业的浓厚兴趣。混凝土的抗压强度通常是通过钻取岩芯并在实验室进行测试来确定的。这种方法相对昂贵，可能需要几天时间才能知道结果。此外，这种方法具有破坏性。因此，为此目的开发了几种非破坏性技术。其中包括：脉冲速度法、表面硬度、渗透、拔出、分离和成熟度技术[1]。这些技术的主要缺点是它们的准确性有限，而且它们并不是完全无损的。
The construction industry has a keen interest in using a nondestructive, real-time, reliable and inexpensive technique for the in-place evaluation of the compressive strength of concrete structures. Compressive strength of concrete is usually determined by drilling a core and testing it in a laboratory. This method is relatively expensive, and it may take a few days for the results to be known. In addition, this method is destructive. Consequently, several nondestructive techniques have been developed for this purpose. These include: pulse velocity method, surface hardness, penetration, pullout, breakoff and maturity techniques [1]. The major disadvantage of these techniques is their limited accuracy, and the fact that they are not totally nondestructive.
