Experimental Study on the Flexural Performance of Hydraulic High Ductility Concrete

Abstract

In order to solving the problem of tolerance in the mixing of water workers’ consolidation processes, Hydraulic High Ductile Concrete (HHDC) was prepared by using lower cost centimeters and TY-PVA fibers. The effects of sand-binder ratio, fly ash dosage, rubber powder dosage and fibre dosage on the performance of HHDC were investigated. The results show that among the four influencing factors, the rubber powder dosage and sand-binder ratio have a more significant impact on the flexural load, with HHDC-1 having the highest flexural load of 3.49 kN. While the fiber dosage and fly ash dosage have a significant impact on the ultimate deflection, with HHDC-7 having the maximum ultimate deflection of 0.60 mm. Each group of HHDC exhibits ductile failure characteristics during the bending process. The conclusion of the study can provide some theoretical support for the engineering application and promotion of HHDC.
