Incorporation of Granite Waste from Diamond Wire Sawing Process into Cement Matrix Concrete

Abstract:

As one of the world leading producers of natural stones for ornamental purpose, mainly marble and granite, Brazil also generates an increasing amount of corresponding wastes. Several alternatives have locally been proposed for the application of these wastes, including the incorporation into cement matrix concretes. In the present work a granite waste, generated by a sawing system composed of sintered diamond in the form of cylindrical beats attached to a steel wire, was incorporated into a cement matrix to be used as building construction concrete. These cement concretes incorporated with up to 30 wt% of granite waste were evaluated in terms of mechanical and chemical properties as well as their environmental impact. The results indicated that 20 wt% incorporation would be a limit for a concrete with acceptable technical characteristics and safe environmental risks.
