Abstract

Civil engineering practice produces functional and esthetic structures but the manufacturing and mining processes that produce construction materials are unsustainable and negatively impact our environment. Construction and mineral wastes constitute over 40% of all waste that are sent to landfill. Accumulation of untreated mineral wastes leads to leaching and contamination, causing significant environmental and health issues. Treatment, management, and valorization of these waste streams is critical for a green, sustainable construction future. This chapter will review current sustainable management and valorization strategies, which transform mineral wastes into cementitious fillers and binders for implementation in construction materials. These approaches include (1) mineral stabilization in an inert matrix, (2) use as a pozzolanic filler, (3) uses in alkali activated and geopolymer cements, and (4) applications for mineral carbon sequestration within construction products. The impacts of these approaches are presented and benchmarked to Ordinary Portland Cement for use in the construction sector. Mineral wastes are shown to present a significant opportunity to develop green materials for construction.
