EFFECT OF MAGNETIZED WATER ON THE PROPERTIES OF CEMENT MORTARS AT THE EARLIER AGES

Abstract

This study had been conducted to investigate the influence of magnetized water on the properties of cement mortars such as initial and final setting time, consistency and compressive strength with various water/cement ratios at the ages of 1 and 7 day. Results of (50) specimens with different shapes had been adopted, which represented mortars specimens having compressive strength ranging from (5.5) to (32.5) MPa, initial setting time ranging from (4) to ( 32) minutes and final setting time ranging from (303) to (546) minutes, by using two types of mixing water , first one is tap water , and the other is magnetized water.The results showed that the use of magnetized water in producing cement mortars lead to increase in the compressive strength and decreasing in the initial and final setting time with compare to use of tap water. Results also showed that the optimum water/cement ratio give best compressive strength under the conditions of this study was (0.45).
