Eco-smart and cost-effective ultra-high performance concrete

Abstract

Cost-effective and sustainable ultra-high performance concrete mixtures incorporate ground granulated blast furnace slag (GGBFS), limestone powder (LP), diatomaceous earth (DE), and/or metakaolin (MK). The composition may include portland cement, sand, ground granulated blast furnace slag, limestone powder, silica fume, and fly ash. The composition may alternatively include portland cement, sand, silica fume, metakaolin, and diatomaceous earth. The powder composition may be mixed with steel fibers, a water reducing mixture, and water. A ratio of limestone power to sand may be 1:15 to 1:7 or 1:10 to 1:8. A ratio of ground granulated blast furnace slag to portland cement may be 1:1 to 1:7 or 1:2 to 1:5.
