Strength-enhanced ecological ultra-high performance fibre-reinforced cementitious composites with nano-silica
An economical and ecological (ECO) ultra-high performance fibre reinforced cementitious composite (UHPFRCC) with a high volume of mineral admixture as part of the binding materials and river sand as the aggregate was designed. The flowability and strength development of ECO-UHPFRCC with various dosages of nano-silica were studied. The effects of nano-silica on the morphology of hardened matrix microstructure and the hydrates characteristics were investigated by SEM, XRD, TG and nano-indentation. The results demonstrated that the mechanical properties of the ECO-UHPFRCC were significantly improved with the increased dosage of nano-silica; its compressive strength exceeded 200 MPa after 3 days of steam curing when mixed with 4% by weight of nano-silica. The static mechanical properties of ECO-UHPFRCC were enhanced as a result of the optimized micro-properties. The mechanism of the effects of nano-silica on the performance of ECO-UHPFRCC microstructure were investigated and discussed as well.
