Abstract: The ultra-high performance cement-based material has the characteristics of high strength,
large load capacity, resource saving, and excellent durability. It is one of the main directions
of the development of concrete technology. In order to realize the large-area application of
ultra-high performance cement-based materials in engineering structures, the problem of high
viscosity must be solved. Micro-bead fpy ash is very little particles, high activity, excellent
water reduction, fine filling properties, low water demand ratio. The micro bead fly ash can
improve the fluidity of concrete, reduce viscosity of the ultra -high performance concrete
mixture, and reduce concrete pumping resistance.
