| dc.description.abstract | Concrete is a heterogeneous material obtained by mixing cement paste (binder) with aggregates (filler), The later constitutes more than 80% of the concrete. Concrete is a macro-material strongly influenced by addition nano-properties such as iron oxide. One of the most important properties of hardened concrete is its compressive strength, which can be quantitatively measured. We have studied effects of different concentrations of hematite (5 to 25 gram weight) at 5 gram intervals) on compression strength of concrete. This work aims to evaluate the use of iron oxide (Hematite) in Portland cement concrete, as a replacement for local sand. Cement mortars with mix proportioning 1:3 were prepared. The water/cement ratio used was about 0.52 for all mix proportions. The compressive strength was measured after 14 days of completion of curing time. Results showed that the compressive strength of the concrete using iron oxide nanoparticles were not equivalent to that of the conventional concrete. Maximum decreasing in compressive strength was about 40%. According to the results of compression strength for conventional and incorporated specimen, the addition of iron oxide to concrete will decreases the compressive strength of concrete due to formation of porosity. | ar |
