Journal ArticleDOI
Surface decoration of carbon nanotubes and mechanical properties of cement/carbon nanotube composites
TL;DR: In this article, the effects of surface decoration on the wetability of multi-walled carbon nanotubes (MWCNTs) and the mechanical properties of the cement paste incorporating these dispersions were investigated.
Journal ArticleDOI
Porosity and microstructure characterization of building stones and concretes
TL;DR: In this paper, the authors compared X-ray computed micro-tomography (micro-CT), water absorption under vacuum and mercury intrusion porosimetry (MIP) to determine the microstructure of concrete and natural building stones.
Journal ArticleDOI
Aggregate-cement paste transition zone properties affecting the salt-frost damage of high-performance concretes
Andrzej Cwirzen,Vesa Penttala +1 more
TL;DR: In this paper, the influence of the cement paste-aggregate interfacial transition zone (ITZ) on the frost durability of high-performance silica fume concrete (HPSFC) has been studied.
Journal ArticleDOI
Reactive powder based concretes: Mechanical properties, durability and hybrid use with OPC
TL;DR: In this paper, the basic mechanical properties, frost durability and the bond strength with normal strength concretes of the ultra high strength (UHS) mortars and concrete were studied.
Journal ArticleDOI
