Effect of Morphologically Controlled Hematite Nanoparticles on the Properties of Fly Ash Blended Cement

Several types of hematite nanoparticles (α-Fe(2)O(3)) have been investigated for their effects on the structure and properties of fly ash (FA) blended cement. All synthesized nanoparticles were found to be of spherical shape, but of different particle sizes ranging from 10 to 195 nm depending on the...

description Several types of hematite nanoparticles (α-Fe(2)O(3)) have been investigated for their effects on the structure and properties of fly ash (FA) blended cement. All synthesized nanoparticles were found to be of spherical shape, but of different particle sizes ranging from 10 to 195 nm depending on the surfactant used in their preparation. The cement hydration with time showed 1.0% α-Fe(2)O(3) nanoparticles are effective accelerators for FA blended cement. Moreover, adding α-Fe(2)O(3) nanoparticles in FA blended cement enhanced the compressive strength and workability of cement. Nanoparticle size and size distribution were important for optimal filling of various size of pores within the cement structure.
