Experience on impact resistance of of ultra high performance steel fiber concrete base on modified ACI 544.2R-89

Abstract

The article presents a method to modify ACI 544.2R-89 for testing impact resistance of Ultra High Performance Fiber Reinforced Concrete (UHPFRC). The article also shows the results of experiments on testing impact resistance of UHPRFC with mean compression strength of 120MPa and 130MPa using 2,0% and 2,5% micro steel fiber and available Vietnamese materials.

Keywords: Ultra High Performance Concrete; Ultra high performance steel fiber reinforcement concrete; UHPC; UHPFRC; impact resistance; ACI 544.2R-99.
