About Possibilities of Strengthening of Epoxypolymer Composites by Modificated Brick Powder

The composites of the epoxypolymer (EP) with the brick powder (BP) are new materials that combine high characteristics with the low price. Herein we discuss about the several such compositions and evaluate some physical characteristics for them. Presented data suggest that BP (at the concentration range from 5 to 50 wt%) increases strength characteristics of the epoxypolymer's compression and abrasion, and reduce his shrinkiness. At the same time, the BP in 10 wt% concentration leads to the frustration and defectation in composite structure. Under the high concentrations of the BP (50 wt%) the plastic deformation disappears, the compression strength increases, contraction decreases, and the destruction of template goes through formation of Chernov-Luders Diagonal; but at the same time usage of high concentrations of the BP leads to increase of swelling of the polymer. The obtained results show that particles of brick powder able to significantly strengthen and structurize the EP-composite, at the same time make it more susceptible for liquid corrosion.
