Dynamic mechanical behaviour and durability of ultra-high performance cementitious composite
Ultra-high performance cementitious composite (UHPCC) with 200 MPa compressive strength was prepared by substitution of ultra-fine industrial waste powder for 60% cement by weight. Compressive impact behaviour of UHPCC with different fiber volume fraction was researched by split Hopkinson pressure bar in four kinds of impact modes. Standard strength of UHPCC under impact was defined. The effects of strain rate, impact times, impact modes and fiber volume fraction on the properties of UHPCC under impact were researched. Results showed that impact resistance of UHPCC was improved with the increase of fiber volume fraction. With the increase of strain rate the dynamic strength of UHPCC was improved. With the increase of impact times the damage of material increased while the standard strength decreased. With the change of impact modes the damage of material on the first impact and the rate of the reduction of peak stress on the second and third impact increased. After a long time freezing-thaw cycle, corrosion and carbonation, results indicated that UHPCC had excellent durability.
