Development of Eco-Efficient UHPC and UHPFRC by Recycling Granite Waste Powder (GWP)
Ultra-high performance concrete (UHPC) is a class of cement-based composites with enormous potentials for sustainable construction thanks to its outstanding compressive strength and cracking resistance. While the former allows saving material volumes and reducing the structural weight, the latter confers unprecedent durability. However, one of the major limiting factor of the industrial use of UHPC drawbacks it is high cost of raw materials. Moreover, UHPC are often characterized by high cement content which not only remains unreacted for a considerable percentage, but it also contributes to the anthropic carbon emission. To reduce the environmental impact of UHPC and initial cost, granite waste powder (GWP) which is locally available as an industrial by-product of the granite quarry in Quebec was used to partially replace cement. UHPC mix-designs with low cement content (400 kg/m3) with 200 kg/m3 of recycled granite powder were produced by assuring satisfactory workability and the compressive strength. The present results compare the developed UHPC and UHPFRC using granite powder with a commercially available UHPC using various indicators.
