New development of ultra-high-performance concrete (UHPC)

Jiang Du et al.

Summary: Ultra-high-performance concrete (UHPC) has superior workability, mechanical properties, and durability compared with conventional concrete, but faces challenges like autogenous shrinkage and insufficient flexural/tensile properties. Research on state-of-the-art technologies for optimizing UHPC mixtures can advance its application and further research.

Effects of nano-SiO2 and nano-Al2O3 on mechanical and durability properties of cement-based materials: A comparative study

Ai Zhang et al.

Summary: The addition of nano materials NS and NA can improve the mechanical and durability properties of cement-based materials. In particular, there is a higher compressive strength growth rate in mortars as the NS content increases. Additionally, the capillary permeability coefficient of cement-based materials can be reduced by adding small amounts of NS and NA.

A comparative study of nano-fillers to improve toughness and modulus of polymer-derived ceramics

Mohammad Mirkhalaf et al.

Summary: The addition of Si3N4 and Al2O3 nanoparticles can significantly improve the toughness and modulus of commercial polysilazane (PSZ) polymer-derived ceramics (PDCs). Additionally, carbon nanotubes are effective in maintaining sample integrity during pyrolysis. The density of PDCs is positively correlated with their modulus and hardness, providing a fast way to assess their performance.

Hydration kinetics and activation energy of cement pastes containing various nanoparticles

Yogiraj Sargam et al.

Summary: The study examined the impact of different types of nanoparticles on the hydration kinetics and apparent activation energy of Portland cement, finding that acceleration effects increased with higher replacement levels but decreased with higher testing temperatures. Additionally, the specific surface areas of nanoparticles played a key role in determining their effectiveness as accelerators at different replacement levels.

Combination usage of nano-SiO2-coated steel fiber and silica fume and its improvement effect on SFRCC

Zhenyu Pi et al.

Summary: This study investigated two effective modification methods, targeting the fiber-matrix interface and the cement matrix, in order to improve the fiber-matrix interfacial properties and the macro-mechanical performances of SFRCC. Various characterization techniques were used to analyze the modification effects, and the results showed that both methods effectively enhanced the microstructure and performance of SFRCC, with the combination usage showing the most improvement in macro performance.

Deposition of nanosilica particles on fiber surface for improving interfacial bond and tensile performances of ultra-high-performance fiber-reinforced concrete

Taekgeun Oh et al.

Summary: This study aimed to enhance the interfacial bond and tensile performance of UHPC containing steel fibers by modifying the fiber surface using EDTA electrolyte solution, cold gas plasma, and nanosilica coating. The test results showed that the surface roughness of steel fibers significantly increased after EDTA treatment and nanosilica coating, improving pullout resistance and tensile performance.

Concentration-induced wettability alteration of nanoscale NaCl solution droplets on the CSH surface

Dongshuai Hou et al.

Summary: The study found that the wetting ability of nanoscale NaCl droplets on the CSH surface decreases with the increase of NaCl mass fraction, as water molecules cluster to form hydration shells around Na+ and Cl- ions, enhancing the associative ability of the droplets. Additionally, particles on the CSH surface attract Na+ and Cl- ions by forming connections with the droplets, further weakening the spreading ability of water molecules on the surface.
