Abstract
With the progress of engineering technology, C50 high-strength coagulation came into being for the needs of actual engineering. This research mainly focuses on the selection of cement varieties and admixtures of C 50 high-strength concrete, so as to realize the optimization research of the mix ratio of C 50 high-strength concrete. The results show that ordinary P.O 42.5 and fly ash admixture can increase the mechanical performance of concrete. However, the concrete compressive strength with the mixed admixture of fly ash and mineral powder is even lower than that without any admixture. On the premise of meeting actual engineering needs, the optimization of the mix ratio of high-strength concrete can not only achieve sustainable development, but also save investment in project economic costs.
