EFFECT OF MICRO-BEAD FLY ASH ON RHEOLOGICAL PROPERTIES OF ULTRA HIGH PERFORMANCE CEMENT-BASED MATERIALS

摘要：

　　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.
