Abstract: In this paper, the Ecological Reactive Powder Concrete (ECO-RPC) was prepared by substitution of ultra-fine industrial waste powder for 60% cement by weight and replacement of ground fine quartz sand with natural fine aggregates as well. The interfacial bonding strength between ECO-RPC matrix and steel fiber, Flexural and compressive strength, fractural energy of ECO-RPC specimens, cured in three different kinds of conditions, were tested. The experimental results showed that the mechanical properties and durability of ECO-RPC with the substitution of 25% ultra fine slag, 25% ultra fine fly ash and 10% silica fume was better than the others, And its compressive and flexural strength is more than 200 MPa and 54 MPa respectively. The formation mechanism of ultra-high performance of ECO-RPC was analyzed.
