FINE CONCRETE CONTAINING WATER, EXPOSED TO MECHANIC AND MAGNETIC TREATMENT, AND FLUIDIFIER
The subject of research is the effect of mechanic and magnetic treatment of different concentrations of the aqueous solution of fluidifier S-3 produced onto the concrete mix rheology, compressive strength and structure formation. Mechanic and magnetic treatment was performed by the pulsed rotor machine equipped with a permanent magnet. It is identified that mechanic and magnetic treatment of the water added into the fluidifier improves the flowability of the concrete mix in comparison with the flowability of the concrete mix prepared absent of treated water, although the amount of the fluidifier meets technical specifications. S-3 fluidifier content in the mix that has treated water is smaller than the same content in a standard mix by several hundreds of times. The concrete mix that has treated water demonstrates highest flowability. The water-to-cement ratio was fixed at 0.4 for all specimens under consideration. In addition, the concrete that has treated water and a minimal amount of S-3 fluidifier (5% of the cement mass) demonstrates that its compressive strength is by far higher than the one of the concrete prepared through the application of the conventional approach that contemplates a standard fluidifier consumption rate. Following a thermal analysis, a thermogravimetric analysis and an X-ray diffractometry, it was discovered that the application of treated water accompanied by the minimal consumption of S-3 fluidifier caused the structure of the concrete cement stone to be more compact, while it demonstrated higher crystallization and stronger interphase interaction. Therefore, considerable reduction in the consumption of S-3 fluidifier, coupled with mechanic and magnetic treatment of the water improves concrete strength properties while concrete flowability does not deteriorate.
