摘要

本文论述了利用

射线反向散射法测定混凝土构件表层密实性的原理、设备和试验结果。试验采用

137

Cs辐射源，源强2.59MBq，探测设备在混凝土中的影响深度约10cm，可测精度0.1g/cm

。对于探测深度、影响边界、工作曲线的率定和探测灵敏度等进行了讨论，并提出了利用铝作标准块的现场标定方法。

Abstract

The principle

instruments and test results to measure concrete surface density by

-rаy backscattering are described. A radioactive source

137

Cs 2.59 MBq was used

the penetration depth in concrete is about 10 cm

and the measuring precision is 0.1g/cm

. The penetration area and depth in concrete

the calibration method and the measurement sensitivity are discussed. A suggestion for in-situ calibration with aluminium as standard specimen is put forward. Finally

some successful examples of in-situ practice are introduced.
