摘要：
The effect of nano-CaCO3 with different contents (i.e., 0, 1, 2, 3, 4% by mass of cement) on the mechanical properties including the compressive and tensile strength of ultra-high performance fiber reinforced concrete (UHP-FRC) was investigated experimentally. It was found that the incorporation of nano-CaCO3 enhanced the mechanical properties of UHP-FRC, and the optimal nano-CaCO3 dosage to enhance the compressive and tensile properties of UHP-FRC was 3%. More specifically, the compressive strength increased by 7.7%, while the tensile strength increased by nearly 40% up to dosage of 3%.
