  • Description: <jats:title>Abstract</jats:title> <jats:p>For cement mixture, water is indispensable and directly affects the performance of cement mixture of raw materials. Based on the research conclusion of alternating electromagnetic field, square wave excitation signal and 50-turn excitation coil were used to activate water through alternating electromagnetic field with different magnetic induction intensity (52.6mT, 97.8mT, 151.2mT, 193.6mT) at different flow rates (0.69m/s, 0.85m/s, 1.05m/s) to explore the effect of activated water on the performance of cement mortar. Through tests, the workability and compressive strength of cement mortar are improved, the water retention is better, and the apparent density is increased. The maximum increase of consistency is 34%, the layering degree is within 20mm, and the compressive strength of 7<jats:sup>th</jats:sup> day, 14<jats:sup>th</jats:sup> day and 28<jats:sup>th</jats:sup> day can be increased by 27.5%, 23.8% and 20.3%.</jats:p>
