“…Nazari et al found that addition of GGBFS content up to 45 wt% results in increased split tensile strength and SiO2 nanoparticles incorporation up to 3 wt%, could also have beneficial effect [27]. Jalal et al in another study reported enhanced split tensile strength of SCC by addition of nano-TiO2 up to 4 wt% [5].…”

“…Figure 4a shows one of the five performed tensile stress-strain curves of Inconel 625 alloy. The inset gives comparison results of the tensile test for Inconel 625 samples in the present work and literatures [25][26][27][28][29][30][31]. Apparently, the tensile strength of different processing samples are not identical.…”

Additive manufacturing (AM) nickel-based superalloys have been demonstrated to equate or exceed mechanical properties of cast and wrought counterparts but their tribological potentials have not been fully realized. This study investigates fretting wear behaviors of Inconel 625 against the 42 CrMo4 stainless steel under flat-on-flat contacts. Inconel 625 is prepared by additive manufacturing (AM) using the electron beam selective melting. Results show that it has a high hardness (335 HV), superior tensile strength (952 MPa) and yield strength (793 MPa). Tribological tests indicate that the AM-Inconel 625 can suppress wear of the surface within a depth of only ~2.4 μm at a contact load of 106 N after 2 × 104 cycles. The excellent wear resistance is attributed to the improved strength and the formation of continuous tribo-layers containing a mixture of Fe2O3, Fe3O4, Cr2O3 and Mn2O3.

“…Moreover, A conclusion that a significant decrease in sorptivity was exhibited when more than 20% replacement of FA was applied [24]. The results, obtained by Jalal et al [25], demonstrated that flowability of SCC, including FA, has been improved due to absorbed water and penetrating chloride ion of longer depth, as mentioned for SF previously. Zhao et al [26] enhanced the initial slump flow on SCC incorporating FA and ground granulated blast-furnace slag.…”

“…Water magnetization has few drawbacks that may hinder using it widely in pre-mixing plants and building construction. One of the main problems is that the magnetization process takes a long time to ensure the required level of magnetization [25]. From the applicational point of view, an effective system should be built from non-magnetic components because of the following: the water is magnetized according to the spontaneous formation and degeneration of colloidal groups of mineral cations in magnetic water, then the water molecules are charged and show diamagnetism (substances that are magnetized in a way opposite to the direction of the magnetic field).…”

A Study for Improving Compressive Strength of Cementitious Mortar Utilizing Magnetic Water

et al. 2020

This research investigates the means to improve the compressive strength of mortar mixtures through using novel mixtures. These mixtures include magnetic water (MW) and fly ash (FA). MW was obtained by circulating tap water (TW) through a magnetic field. The magnetization duration was represented by the number of cycles, the content of FA was replaced with cement, and the super plasticizer percentage (SP) and the curing age were used and evaluated experimentally for producing the mortar mixtures. Mortar flow, crushing compressive strength, and ultrasonic pulse velocity (UPV) tests were applied to evaluate the performances of mixing characteristics. The results demonstrate that the MW-treated mortar mixtures show higher compression strength results than those prepared by TW. The compressive strength was increased up to 60% with 150 cycles, a dose of 0.5% of SP and no FA content at the age of 56 days. The dose of SP can be cut down by a maximum of 40% to 50% in cementitious mortar. the workability was enhanced by a percentage of 70%.
