“…When water comes in contact with a glass container, the magnetic effect is transferred to the water molecules. The revision of previous research papers has revealed that water treated with either the north or south pole or the two poles together have different physicochemical properties [24][25][26][27][28][29][30]. Many studies, however, do not differentiate between water treated with the south pole, north pole, or both poles [25,28,29].…”

Magnetic treatment technology for concrete mixing water is a cost-effective and environmentally friendly approach that can enhance the performance and durability of cement-based materials. This technology aligns with the principles of sustainable development. In their studies, researchers have utilized static magnetic fields (SMF) of varying intensities to treat regular water and produce magnetically treated mixing water (MTMW) for a specific duration. Various research laboratories have successfully employed MTMW in the production of cement-based materials such as cement paste, mortar, ordinary concrete, foam concrete, self-compacting concrete, and rubber concrete. The main objective of this investigation is to review previous research that evaluated the impact of MTMW produced using different methods on the fresh, hardened, durability, and microstructure properties of cement-based materials. Most studies revealed that magnetic treatment technology improves physical and chemical properties of regular water, including solubility, surface tension, and conductivity. Regarding cement-based materials produced with MTMW, most investigations have demonstrated a significant enhancement in mechanical strength, durability, and microstructure. However, it seems that some researchers may have exaggerated their findings regarding the effect of MTMW on mechanical properties. Consequently, further research is needed to validate these results. I recommend considering the utilization of the MTMW technique for all cement-based materials to enhance their mechanical strength and durability performance.

Concrete deterioration due to sulfate attack is one of the factors for early failure. Considering that sulfates in aggregates are the most important problem related to concrete in the cities of the Middle East and especially Iraq, so there was a need to develop a device to enhance the strength of concrete. In the current experimental research, we sought to discover how to treat and improve the performance of fresh concrete containing high percentages of sulfate salts in sand, using a magnetic field generation device with an electrical principle made locally. The work included the beginning of casting 27 models of concrete cubes that were treated using different magnetic intensities and examined to select the highest strength, which was 3000 Gauss, which was adopted in this research. Two groups of mixtures were prepared and poured using 72 cubes and prisms. The first group was divided into two reference mixtures not treated with a magnetic field. Two types of sand with different sulfate ratios with resistant Portland cement were used. The second group was prepared using the same method and working conditions, except for treating the concrete mixture with electromagnetic fields. The results showed an encouraging improvement in the compressive strength of magnetically treated concrete, where the rates of increase in compressive strength were (5.45, 5.5, 5.7%) with 0.15% SO3, and (7.2.7, 4.6%) with 0.6%. SO3 for a period of (7.28 and 90) days, respectively, compared to control mixtures. This technology can be applied during the pouring process on job sites.

This paper mainly explores how waste slurry as mixing water affects the properties of C80 concrete. The waste slurry was collected from a mixing station. Two types of C80 concrete were prepared with different mineral admixtures: type I concrete mixed from 15% fly ash and 20% slag powder, and type II concrete mixed from 20% fly ash and 10% silica fume. The properties of the two types of concrete were evaluated in terms of working performance, mechanical properties, and durability. In addition, the influence of waste slurry on microstructure of concrete was analyzed through X-ray diffraction (XRD). The results show that, with the growing content of waste slurry, slump and expansion were declining; the initial and final setting times gradually increased, but the increments were not significant; with the growing content of waste slurry, the 7d compressive strength of type I concrete stayed below that of reference concrete, and gradually decreased, but the later compressive strengths increased rapidly; the 7d compressive strength of type II mineral admixture concrete gradually increased, while the later compressive strengths increased first and then decreased. Besides, the addition of waste slurry enhanced the resistance to chloride ion penetration (CIP), and increased the carbonization depth of concrete. The 7d XRD peak of using tap water as mixing water was slightly higher than that of using waste slurry as mixing water; the 28d XRD peak of the former was slightly lower than that of the latter. The research provides reference for applying waste slurry in concrete production.
