Effect of electron water curing and electron charging curing on concrete strength
By charging normal water under an appropriate electric voltage, electron water can be produced. With its small molecule cluster and high activity, the water has been found to have applications in many fields. This study showed that: 1) by curing concrete specimens in electron water, concrete strength was increased by at least 5% and by more than 15% at early ages in comparison to that of the concrete cured in normal water at the same temperature; and 2) by electron charging curing the strength of concrete could also be improved, especially its 1-day strength, which was increased by as high as 50% relative to that of control specimens. The possible reason for the strength increase of concrete by the both curing methods is that the curing water and the water in concrete both have small molecule clusters and high activity caused by the charging treatment, resulting in the improvement on cement hydration and the decrease in average pore size and the volumes of large pores of concrete.
