Description
An experimental apparatus and a prototype have been designed to measure density of concrete according to the principle of backscattering and transmission of γ ray with a measuring depth up to 500 mm. Through experiments, the source, detector, optimal geometry, calibration system, math model, calculating programs, electronics and microcomputer were established. Thirty sets of ND-50 nuclear density gauge have been trial-produced or reproduced, and applied to control the quality in roller compacted concrete dam (RCCD) for at least 5 x 105 m3 in more than ten hydraulic and hydroelectric projects
