CO2-footprints and costs of commercial UHPCs are high. Industrial by-products are hardly used in UHPCs. A key reason is the lack of knowledge on the mechanical and durability properties of UHPCs with by-products. In this thesis, the properties of UHPCs incorporating by-products, namely, slag (GGBS), fly ash (FA), and gold-mine tailings (GT), are investigated. UHPCs with up to 60% GGBS or FA, as cement-substitute, and UHPC with 100% GT, as sand-substitute, exhibit strength above 120MPa. Durability performances of UHPCs with by-products are comparable to or better than the durability of UHPC without by-products(except for UHPC with 70% FA).
