Hydrometer법에 의한 밀도 값과 시험 성적서간 상관분석을 통한 플라이애시의 품질분석
Analysis of FA Quality through Correlation Analysis between Density Measured with the Hydrometer Method and the Test Report
초록
Basic lot tests via textile and visual examinations are conducted on FA carried into in-service RMCs. The system of evaluating quality by taking samples from each lot and examining them, or evaluating quality based on the score reports submitted by the deliverer during in-service training have on some instances been called into doubt as to their reliability in evaluating the quality of FA. Therefore this study sought to measure the density value of FA that is actually delivered to RMC companies according to the Hydrometer method and analyze its correlation to its test scores, to in turn analyze the reliability of the test reports and the characteristics of the quality of FA. The results led to the conclusion that the fineness and density marked on the score reports were problematic, and therefore accurate experiments and adjustment of significant digits on the test report are necessary.
