抗拉法检测混凝土强度
|
摘要
结构混凝土强度无损检测技术是自20世纪30年代发展起来的用于检测混凝土强度的方法。从那时起,人们就在寻找简单、可靠的检测方法,从回弹法、超声法、钻芯法到拔出法,虽然技术比较成熟,但因为影响因素较多,离散性较大,因此都存在着很大缺陷。结合上述方法的优点,同时针对它们的缺点,提出了以建筑底胶和AB胶作为黏接剂、抗拉法检测混凝土强度的新技术。
Nondestructive evaluation methods of structure concrete strength developed from 1930s,which can test the concrete strength.Then people began to look for the simple and dependable examination method,from rebound and ultrasonic and core-drilling to pullout method,although the technique is very mature,because of many influence factors and disperse,these methods are of many blemish.The advantages of above-mentioned method are combined,aiming at their weakness at the same time,connecting with the building bottom gum and the AB gum as the adhesive,tensile strength method is studied.
