Paper Title:
Cutting Forces in Sawing Process of Reinforced Concrete
  Abstract

Three kinds of typical concrete materials were tested involving cement concrete, steel fiber reinforced concrete and ferroconcrete. The 3-direction cutting forces acted on the diamond sawblade were measured with varied cutting speed, feed speed, depth of cut and diamond segments. The measurements show that during the whole cutting process, the curve of cutting forces fluctuate intensely, which indicate the differences of the cutting process of heterogeneous mixture of the concrete. Because of the larger amplitude, the average values of cutting forces are much smaller than that of peak values. The cutting forces increase with the increase of feed speed, in reverse, decrease with the increasing of cutting speed. When the strength grades of the concrete materials are the same, the cutting forces of ferroconcrete and steel fiber reinforced concrete show the higher value than those of cement concrete. The cutting forces of sawblade with brone-cobalt based bond are greater than those of sawblade with cobalt based bond in sawing concrete process. Adding cobalt content in matrix, the cutting force can be decreased when sawing cement concrete. While sawing steel fiber concrete and ferroconcrete, the cutting forces can be decreased by reduction of cobalt content and increase of iron content in matrix.
