Magnetic activation water Technology improved reused crumb rubber cement mortar

This experimental study explores the impact of Magnetic Activation of Water (MAW) on the fresh and hardened properties of Reused Crumb-Rubber Mortar (RCRM). Eight different mortar formulations were produced, comprising four variants using potable water (DW) and four utilizing MAW, with varying percentages of Reused Crumb Rubber Sand (RCRS) substituted for natural sand at rates of 0%, 4%, 8%, and 12%. The analyses of fresh properties indicated that MAW effectively reduced entrapped air and improved the consistency of the RCRM mixtures. In terms of hardened properties, MAW demonstrated a significant enhancement in compressive strength and hydration kinetics of RCRM compared to those made with DW. This innovative approach of employing magnetic activation not only addresses compatibility and heterogeneity challenges typically associated with rubber-cement mixtures but also offers a viable solution for incorporating waste rubber into cement composites. Ultimately, this research presents a promising avenue for improving the mechanical and physical characteristics of recycled materials in sustainable construction practices.
