GROUP TEST ON SIEVING AND SLURRY ANALYSIS
| 项目名称： | GROUP TEST ON SIEVING AND SLURRY ANALYSIS |
| 摘要： | IN A GROUP ANALYSIS THE ACTUAL ERRORS (REPEATABILITY AND COMPARABILITY) WHICH OCCUR IN THE TESTING OF FROST BLANKET MATERIALS ARE TO BE DETERMINED. BY INTRODUCING THE MINERAL CRITERION FOR THE EVALUATION OF THE FROST RESISTANCE OF AGGREGATE MIXTURES, THE ACCURACY OF THE SLURRY ANALYSIS WILL BECOME MORE IMPORTANT. 5 MATERIAL SAMPLES (GRADED MIXTURES, CRUSHED ROCK, GRAVEL SANDS) ARE BEING TAKEN IN CONSULTATION WITH THE BVFA ARSENAL, CAREFULLY DIVIDED, AND SENT TO 15 NATIONAL AND/OR AUTHORIZED TESTING CENTRES FOR EXAMINATION. THESE LABORATORIES ARE TO CARRY OUT DETERMINATIONS OF THE GRADING CURVE AND OF THE PROPORTION OF FINES BELOW 0.02 MM. THE RESULTS ARE BEING STATISTICALLY EVALUATED AND THE TESTING ERRORS CALCULATED, AND IF NECESSARY THE PRESCRIBED TESTING PROCEDURES ARE BEING IMPROVED. |
