| Abstract: |
| This study investigates Compressive strength,pore structure and carbonation properties of concrete mixed with alkaline redox potential water(ARPW) were investigated.A miniature electrolyzer made up of diaphragm electrolytic cells was manufactured to produce ARPW.Electric field strength of 320 V/m and flow rate of 80 mL/s were used as electrolyzing coefficients.Results show that the compressive strength of concrete mixed with ARPW raised 10% at early age and 20% at the age of 28 d.General porosity decreased ... |
