The Influence of Stray Current on the Maturity Level of Cement-Based Materials

This work reports on the influence of stray current on the development of mechanical and electrical properties of mortar specimens in sealed and water-submerged conditions. In the absence of concentration gradients with external environment (sealed conditions) or in their presence (submerged conditions), compressive strength and electrical resistivity change due to: cement hydration alone; cement hydration, affected by diffusion (including leaching-out); or cement hydration, simultaneously influenced by diffusion and migration. The results are compared to equally conditioned control specimens, where stray current was not involved.
