| Abstract | ||||
| Nano ferrite/cement composites (NFCC) have been prepared by adding different weight ratios of Nano ferrite (N.F) ranging from (1 up to 4%) cement. This study is aimed to evaluate the effect of addition of N.F on the mechanical behavior of NFCC and study the performance of cement pastes and cement mortars mixed with Nano ferrite (N.F) when exposed to elevated temperatures of 200 oC and 400 oC, for firing period of two hours. Compressive strength test showed valuable enhancement in mechanical properties of NFCC with increasing N.F loading ratio. The obtained minerals of Cu-Zn ferrites nanoparticles were identified by using X-ray diffraction (XRD) and the morphology of N.F was determined using transmission electron microscopy (TEM). The microstructure of the NFCC was characterized by means of scanning electron microscope (SEM) analysis. The addition of N.F by about 1% enhanced the compression strength to about 52 % for cement paste and1% enhanced the compression strength to about 35% for cement mortar. The results indicated that cement pastes and cement mortars mixedwith N.F are more able to resist elevated temperature than pure cement pastes. | ||||
