Rapid Runway Repair Program Subtask 1.08 - Concrete Cutting Equipment Evaluation.

Abstract

Diamond saws were identified in earlier studies as a promising technology for cutting concrete for bomb damage repair efforts. Diamond saw blade design parameters (metal bond; diamond type, concentration, and mesh size) were investigated to develop an optimum rapid cutting blade. Blade performance was measured in terms of cutting rate, power requirement and wear performance. Cutting rates as high as 4 sq. ft. min for a 7-inch deep cut were achieved requiring 34 horsepower. At these high cutting rates, the 24-inch diamond saw blades developed gullet cracks. Data from the test program is interpreted regarding the feasibility of several possible diamond saw systems for obtaining cutting rates of 20 sq. ft. min. (Author)
