Nowadays, the application of ultra-high-performance concrete (UHPC) has had a significant proliferation worldwide. However, its high carbon footprint and costs, due to its high cement, silica fume, quartz dust, and fiber contents, can be mentioned among its main drawbacks. It is the purpose of this review paper to summarize and analyze the contributions of the research performed in Colombia in the last 2 years on the optimization of UHPC dosages to render its costs and carbon footprint a minimum. The results of this review demonstrated that it is possible to obtain an eco-friendly and low-cost UHPC cementitious matrix by using mineral admixtures available in the Colombian market. Furthermore, the referenced pieces of research also showed that they could achieve excellent ductility parameters by adding less than 2% of total volume fiber to the optimized UHPC matrix.
