Stray Current-Induced Development of Cement-Based Microstructure in Water-Submerged, Ca(OH)2-Submerged and Sealed Conditions

This work reports on the development of microstructural and mechanical properties of mortar cubes under the synergetic action of stray current and various environmental/curing conditions. The study refers to specimens cured for 24h only, followed by a 112 days period of partial or full submersion in water or alkaline medium. Additionally,...

Electrical Current Flow and Cement Hydration: Implications on Cement-Based Microstructure

Stray current is an electrical current “leakage” from metal conductors and electrical installations. When it flows through cement-based materials, electrical energy is converted to thermal energy that causes increasing temperature due to Joule heating phenomena. The aim of this paper is to shed light on the influence of electrical current flow...
