Development of electrolyzed water based concrete: a new approach for early strength gain

In this paper the effects of electrolyzed water in controlling the early age properties of concrete was investigated. The concrete samples were cast using normal and 30 min electrolyzed water. The performances of concrete samples were evaluated by the means of bulk density, apparent porosity, and compressive strength measurement. Analyzing the results, the bulk density and the apparent porosity ofelectrolyzed water based concrete (EC) are found to be greater (1.37 % cured for 3 days and 1.66 % cured for 7 days) and less (6.18% cured for 3 days and 7.56 % cured for 7 days), respectively, as compared to normal water based concrete (NC). Based on the mechanical property analysis it is anticipated that EC achieves greater compressive strength (28.54% cured for 3 days and 20.53% cured for 7 days) than that of NC. The better performance of EC is primarily governed by the accelerated hydration reaction in the presence of hydroxyl ions in electrolyzed water, which, in turn, leads to develop a matured microstructure as justified by SEM analysis.
