Recycled powder as filler admixture in cementitious systems : production and characterization [PDF]
In concrete production, aggregate represents almost 75% of the materials used. The exploitation of natural sources for this purpose also causes an environmental impact, while deposition of wastes from construction industry pollutes soil and water.
