“…The highest amount of pores in the concrete structure occurred in the control mix; i.e., using magnetized water instead of regular tap water led to a significant improvement in the microstructure of the concrete mixes, which agrees with previous studies [ 6 , 8 , 15 , 16 ]. This greater density of concrete mixes with magnetized water may be attributed to the higher degree of cement hydration, as a result of more interaction between the cement particles and water molecules.…”

“…This is in good agreement with the results of Ahmed [ 15 ], which used magnetized water instead of regular tap water, and found a significant improvement in the microstructural properties of concrete mixes. Consequently, the structure of concrete with magnetized water becomes denser, and lower amounts of pores can be seen in concrete with magnetized water compared to concrete with regular tap water [ 6 , 8 , 15 , 18 ]. These differences explain why the magnetized water can increase the durability properties of concrete mixes.…”

“…Water chemistry (mineralogy, types of ions present, total dissolved solids, pH, etc.) is a key factor in concrete production that affects the mechanical properties of concrete, namely its compressive strength, flexural strength, water absorption, workability, and durability [ 6 , 7 , 8 , 9 ]. However, few investigations had been conducted on the effect of magnetized water on the mechanical properties of concrete mixes.…”

“…Magnetized water has different mechanical, electromagnetic, and thermodynamic properties compared to regular tap water [ 8 ]. Due to these specific properties, the use of magnetized water has been increasing in different applications such as in industrial, environmental, medical, and agricultural fields due to the development of magnetic devices.…”

Effect of Magnetized Water on the Mechanical and Durability Properties of Concrete Block Pavers

In this research, the effect of magnetized water on the mechanical and durability behavior of concrete block pavers was investigated. For this purpose, a total of five mixes were prepared with water that passed through a permanent magnetic field 10, 20, 40, and 80 times at a constant speed of 2.25 m/s. Compressive strength, splitting tensile strength, flexural strength, resistance to sulfuric acid attack, water absorption tests, and Scanning Electron Microscopy (SEM) analyses were conducted. The compressive strength, splitting tensile strength, and flexural strength test results showed a significant positive effect of using magnetized water. The remaining tests also revealed that using magnetized water increases the resistance of concrete block pavers to sulfuric acid attack and decreases their water absorption.

“…This can be explained as follows: Due to the use of TW, the percentage of SP is very effective as the water particles are distributed for the reaction across the cement particles, but when using MW, which makes the same effect by rearranging the water molecules, there is no need to excess the amount of SP. This is because MW reduces the dose of SP by about 30% in concrete [36]. Therefore, MW can reduce the SP dose to about 40% to 50% in the mortar considering FA% and the number of cycles as illustrated in Table 7.…”

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%.

In order to investigate the effect of double bond content in the crosslinkers on the performance of superplasticizers, three different crosslinked polycarboxylate superplasticizers were synthesized herein with various respective crosslinkers. Their impacts on the fluidity, absorption, and hydration behavior of cement systems were studied. The results showed that the polymer, which was synthesized using a crosslinker with four double bonds and five/six double bonds, had higher fluidity and the highest fluidity reached up to 395 mm at W/C of 0.35. Additionally, thermogravimetric analysis and hydration heat tests showed that the crosslinked polycarboxylate superplasticizers could prolong the hydration process of cement slurries. Among these three kinds of crosslinked polycarboxylate superplasticizers, the induction period of cement slurry containing the polymer with crosslinker of four double bonds was significantly extended to facilitate the processing of the concrete. The purpose of this study is to provide strategies for studying high-performance polycarboxylate superplasticizers with novel topological structure.
