Concrete sawing waste is sludge (SL) containing small concrete particles and water. The idea of presented work is application of the sawing sludge in concrete production as micro filler. Micro particle size distribution of sludge was determined and compared with traditional micro filler. Experimental work included preparation of traditional and self-compacting concrete containing sawing waste. Test results indicate good workability characteristics of the concrete mixes containing sawing sludge. In the case of self-compacting concrete containing high dosage of sludge, reduction of mechanical properties was recorded. Experimental results indicate that it is possible to find the optimum dosage of sludge, which ensures the required performance characteristics of concrete.
