innovative multifunctional nanoengineered concrete showing an unprec­ edented range of enhanced properties when compared to standard concrete, is reported. These include an increase of up to 146% in the compressive and 79.5% in the flexural strength, whilst at the same time an enhanced electrical and thermal performance is found. A surprising decrease in water permeability by nearly 400% ...

19/07/2021  Ultimately, entrained air voids affect the pore size distribution, particle distribution and even the ITZ of the pore structure of concrete. More studies worked on the influence of air voids on the microstructure of concrete, especially the influence on the interfacial transition zone (ITZ). H. S. Wong studied the air void–paste interface with BSE and pointed out that the porosity near the ...

In this study, high performance concrete (HPC) containing two types of nanoparticles: carbon nano tubes (CNTs) and nano silica (NS) and hybrid nanoparticles (CNTs + NS) were prepared. The compressive strength, phase composition, pore size distribution, surface area, surface morphology and microstructural characteristics were investigated at 7 and 28 days of hydration.
