Abstract

The paper presents water uptake and tensile properties of epoxy filled with inorganic fillers having different
reactivity to water, namely Portland cement, fly ash, and calcium carbonate (CaCO3) particles. Portland cement
and CaCO3, respectively have the highest and the lowest water reactivity. The filler volume fraction was ranging
from 0 to 25 %. The results showed that for the reactive filler, with the increase of volume fraction, the water
uptake increased and behaved as non-Fickian, whereas for the less reactive filler, the water uptake decreased and
behaved as pseudo-Fickian. In dry condition, with the increase of volume fraction, the elastic modulus and
tensile strength increased and tended to decrease, respectively, regardless of the filler type. However, in wet
condition, the positive effect of filler on the elastic modulus diminished due to excessive plasticization of the
matrix, and the reduction of elastic modulus of the most reactive filler is the lowest.
