“…Iron oxides classified as coloring admixture, in addition it improve some mechanical properties as out lined in [2], which conclude that, The using of nano ZrO 2 , Fe 3 O 4 , TiO 2 and Al 2 O 3 with constant content will enhance the mechanical properties of fresh and hardened concrete as compressive strength, indirect tensile strength and durability. The same result is adopted in [3], work; it can be used, iron oxide , as pigment with percent less than 4% in concrete.…”

Study discuss the effect of using commercial red and black iron oxides (RIO and BIO) as a concrete admixtures in percentages do not exceeded 2.5% of each oxide from the amount of cement, this study tested the effect of every portion from each oxide at different ages on the compressive strength as well as the workability represented as a values of slump. We conclude that the optimum portion of RIO is 2.5%, but for BIO is 1%, while the proposed uses of RIO in concrete technology are retarder through slump increment reach to 50%, coloring material and mineral admixture through Compressive Strength increment (7-365 days) 5.5-12.8%. On the other hand BIO will propose as, coloring material and mineral admixture through Compressive Strength increment (7-365 days) 22.2-30.8%. SEM-images are clearly show the formation of Calcium hydroxide phase at 7-days while at 1-year the C-S-H phase is a predominate one, in both cases of RIO and BIO. XRD-pattern is supported the results outcomes through SEM-images.

“…They concluded that nano silica led to significant consumption of portlandite (CH) in the pozzolanic reaction. On the other hand Shekari et al [2] observed an improvement in the mechanical properties of high performance concrete by incorporating nano alumina in concrete. Nazari et al [3] determined that nano titanium oxide act as nanofillers and improves the pore structure of self-compacting concrete.…”

Abstract-Carbon Nanotubes (CNTs) are basic carbon consisting of curved graphene layer which consists of a single layer of atoms in a combined hexagonal structure. After plenty of years several characterization of the carbon Nanotubes has become very popular in various applications in civil engineering. Carbon Nanotubes shows good results in terms of mechanical properties of cement mortar when added to it. Literature has showed that carbon Nanotubes can be used in the manufacture of the concrete and the cement pastes. This paper represents the summary of the various research works on the usage of the carbon nanotubes in cement paste, mortars and concrete.
