SOME EXAMPLES OF MAGNETIZED WATER IMPACT ON CONCRETE MIXTURE

Impact of magnetized water on concrete strength at compressing

As is seen from the above examples, tension strength is always higher than compression strength. In other words, ratio between tension strength at breaking and compression strength in concrete made with magnetized water increased by 25%. It can be explained by a more homogenous lattice of new formations of hydrated cement minerals, mixed with magnetized water. It is worth mentioning that the same phenomenon happens in ceramic materials. Increased tension strength of concrete leads to an extra effect of saving cement, additives and thermal energy when magnetized water is used for concrete, for which tension strength is vital.

But even when compression strength is the main factor for concrete, statistically relevant confirmation of increasing ratio of concrete tension and compression strength allows to increase calculated resistance of concrete at tension in standards for designing concrete construction. It would reduce rods' usage and the required value of their initial tension in elements of the first and second categories of crack- resistance. Requirements for horizontal rods, fixed as calculated for horizontal strength, for crushing and other cases would also drop. Reduction of rods' usage is approximately proportional to increasing of concrete tension strength.
