“…It offers a handy framework that enables an analyst to pick a suitable technique that might be applied to test the strength of cements. Largeau et al [23] studied how iron powder (Fe 2 O 3 ) affected the strength, workability, and porosity of binary blended concrete. The cone Abrams method was used to assess the new composite concrete's workability.…”

The reliance on inferior on cement products for the construction of housing projects and other civil engineering infrastructural facilities has led to a number of building and other structural failures in Ghana over the years. The manufacturing of concrete utilized in the building of various structural member, such as columns, beams, slabs, footings and wall, was negatively impacted by the use of low-quality cements, rendering them unable to sustain any loads placed on them. Another observation made from the cement used was the inadequate proportioning of the chemical compounds during the manufacturing process which has negatively affected the setting of the concrete contributing to poor performance of structural elements in buildings and other infrastructural projects. In this research, the impacts of the variations in chemical constituents including SiO2, Al2O3, Fe2O3, Na2O, K2O, CaO, MgO, and SO3 in the different brands on setting times of cement and workability of fresh concrete were examined. The Vicat apparatus and the slump apparatus set-ups were used to measure the setting time and concrete workability respectively. It was found that the majority of the chemical compounds of the various cement brands evaluated in this research provided appreciable setting time as well as typical and acceptable consistencies. Most cement brands showed initial and final setting times between 30 and 271-306 minutes for cements in the 32.5R class. The initial and final setting times generated by the test were likewise observed to fall within 30 minutes and between 172-263 minutes, respectively, in the 42.5R class of cements, where a similar pattern was also observed. It was noted that for the same water-cement-ratio in all the concretes from the different brands of cement, good workability was obtained.

“…Iron dust used for the study is the waste produced from the iron ore-based industries [3]. This iron waste is usually used for landfills for its disposal and has been very environmentally dangerous as the heavy metals from this iron ore waste gets into the earth and subsequently into the underground water polluting it [4][5]. So, researchers found the novel use of this waste as a replacing material for the concrete.…”

Ferrock is the commercial name given by the Dr Stone working with university of Arizona which holds the patent on this novel material. This is an alternative material developed for structural applications in place of concrete. In this paper, ferrock mortar is prepared with various solids such as iron powder, iron dust, cement and fly ash to establish the optimum combinations of solids for preparing the high strength ferrock systems. Iron dust in the form of powder (size less than 90 microns) and fine aggregate (size between 150 microns to 2.36mm) is used in the study to develop the iron carbonate matrix which is major binding material in ferrock. For the process of iron carbonation, carbon dioxide is prepared from the chemical reaction of sodium bicarbonate and acetic acid. Iron dust cubes are carbonated to form iron carbonation matrix upon fusion. This material has very high strength than the references cement mortar samples.

“…A notable positive effect of both red and black iron oxide particles on slump and compressive strength (up to 22–30%) was reported. Recently, Largeau et al [ 25 ] investigated the effect of Fe 2 O 3 on the strength and workability of a Portland cement concrete. They found that fine Fe 2 O 3 particles, ca.…”

Effect of Iron (III) Oxide Powder on Thermal Conductivity and Diffusivity of Lime Mortar

et al. 2021

One of the challenges in construction is the improvement of energy efficiency of buildings. Development of construction materials of low thermal conductivity is a straightforward way to improve heat isolating capability of an enclosure. Lime mortar has a number of advantageous and peculiar properties and was widely used until the “irruption” of Portland cement. Currently, lime mortar is still used in restoration of traditional buildings or, according to the urban regulations, in catalogued constructions. The goal of the present study is the improvement of the heat isolating capability of lime mortars. The strategy of this work is the addition of iron (III) oxide powder, which is one of the possible components forming the cements, to a base lime mortar. The reason to choose Fe2O3 was two-fold. The first reason is low thermal conductivity of Fe2O3 compared to lime mortar. The second reason is that the low solubility and small size of iron (III) oxide particles have an effect on the thermal conductivity across the lime particles. The effect of iron (III) oxide powder on the thermal conductivity has been experimentally determined by the hot-box method. It has been found that the insulating capacity and thermal inertia of lime mortar is improved significantly by the addition of Fe2O3 powder, increasing the energy saving of the enclosure.
