Method for judging quality grade of regenerating coarse aggregates for concrete
The invention discloses a method for judging quality grade of regenerating coarse aggregates for concrete. The method mainly comprises the following steps: (1) confirming evaluation indexes of the quality grade of the regenerating coarse aggregates for concrete; (2) establishing a subordinating degree function; (3) measuring the measured value of each evaluation index; (4) confirming the subordinating degree of the evaluation indexes of the quality grade of the regenerating coarse aggregates for concrete to each of the quality grades; (5) confirming the weighting of each quality evaluation index; (6) calculating a comprehensive grade for the quality grade of the regenerating coarse aggregates for concrete; and (7) judging the quality grade of the regenerating coarse aggregates for concrete. The method for judging the quality grade of the regenerating coarse aggregates for concrete provided by the invention has the characteristics of scientific and reasonable property, convenient and feasible operation, relative accurate judging result and the like, the quality grade of the regenerating coarse aggregates for concrete can be objectively judged through quantum calculation, and the influences of the subjective factors on the judging result are reduced.
