There are presented the experimental results of the activation of water in magneto fluidized layer. Activated water is used as mixing water for a concrete mix consisting of sand and cement. Sand and cement were also activated in the magneto fluidized layer. Magneto fluidized layer is a suspension of needle-shaped ferromagnetic elements in a rotating electromagnetic field. As a result of intense collisions between ferromagnetic elements and sand and cement particles, the components of the concrete mixture are crushed. As a result the reactivity of sand and cement increases, which makes it possible to increase the strength of concrete by almost 2,5-3 times. It is shown that the activation of water in the magnetic fluidized bed can further increase the compressive strength of concrete by 15-20%. The use of activated water accelerates the setting time of concrete. When using activated water as water for mixing concrete components, the maximum strength is already observed on the 14th day of hardening of the concrete compared to the usual conditions for 28 days. |
