A PRELIMINARY STUDY OF THE PROPERTIES OF SELF-COMPACTING CONCRETES MIXED WITH ALKALINE REDOX POTENTIAL WATER

摘要：

This study investigates the compressive strength and workability of self-compacting concrete mixed with alkaline redox potential water (ARPW) for the first time. A miniature electrolyzer made up of diaphragm electrolytic cells was manufactured to produceARPW.Water is electrolyzed at the electric field strength of 320V/m and the flow velocity of 80ml/s in the experiments. Results show that, compared to tap water samples, the compressive strength of self-compacting concrete mixed with ARPW increased by 15％ at the age of 28 days and the workability of it enhanced significantly, indicating that the adding of ARPW helps improving the properties of self-compacting concretes.
