Examining the Impact of Magnetic Field on Compressive Strength of Cement Paste with Quartz Aggregate and Zeolite

The use of intelligent or adaptable materials and structures for the optimal use of materials and space is one of the new technologies that has recently become very popular in the construction industry of concrete structures. In this research, one of these technologies in the concrete industry was investigated. Samples containing piezoelectric aggregate (quartz) cause internal reactions by receiving a magnetic field during load application, which were studied in this study. The magnetic field affects the cement mortar containing piezoelectric aggregate. The compressive strength of mortar containing quartz aggregate and zeolite powder under magnetic field was significantly increased compared to the control sample which did not contain quartz aggregate and zeolite and without magnetic field. Compressive strength under magnetic field increased by 100% in some samples. The researchers also found that the interaction effect of increasing the replacement percentage of quartz and zeolite and applying a magnetic field had an optimal point. In most samples in this research, increasing the percentage of Quartz and zeolite or magnetic field, resulted in increase in compressive strength up to a point, however, after that optimum point it started to decrease.
