An Approach of Producing Ultra-High-Performance Concrete with High Elastic Modulus by Nano-Al2O3: A Preliminary Study

Abstract: Ultra-high-performance concrete (UHPC) has promising applications in civil engineering. However, the elastic modulus of UHPC is relatively low compared with its compressive strength, which may result in insufficient stiffness in service. This work was carried out to explore the feasibility of producing UHPC with high elastic modulus by nano-Al2O3 (NA). Based on particle densely packing theory, the initial mixture of UHPC was designed via the modified Andreasen and Andersen model. An experimental investigation … Show more

“…More significant amounts of nanoparticles were more likely to clump together, impeding concrete dispersion. Because of this, the mechanical characteristics of concrete somewhat decreased when nanomaterials were added in quantities higher than recommended [31,32].…”
