Abstract:
A new type of eco-friendly BUHP has been developed through the use of mixed glass with optimized particle size distributions. By an optimized use of mixed glass, this BUHP has the advantage of being 50% cheaper and emitting about 50% less greenhouse gases per m3, while being as efficient, or even more, than a conventional BUHP. This cost reduction is achieved by reducing the use of cement and high-cost materials (silica fume, quartz powder, and quartz sand). These materials are partially replaced by mixed glass particles with well-prescribed sizes. In addition to the patents already obtained in the United States, Europe and Brazil, Canadian Patent was also granted. This patent is currently used by a very large North American group leader in precast concrete. Some field projects will be presented in this session.
