Abstract |
This study reported the effects of labware glass cullet on the properties of porcelain
stoneware tiles. Five formulations of porcelain stoneware tiles (containing 0, 3,
6, 9, 12% borosilicate glass cullet) were prepared by adopting three different
sintering temperatures (1100o, 1150o, 1200oC). The physical, microstructural and
mechanical properties were analyzed. X-ray diffraction analysis ensured the
presence of different crystalline phases in the samples. Morphological analysis
also confirmed the results obtained from the XRD analysis. However, the density
of the specimens increased within their operating parameters. Addition of glass
cullet in the tiles increased the kinetics of the sintering process resulting in lower
open porosity. Water absorption value of the samples sintered at 1200oC remained
within the tolerance limit (~0.5%). The lowest water absorption value (~0.10%) as
well as the highest linear shrinkage value (~8.9%) were observed in the sample
containing 12% glass cullet. Moreover, the usages of 12% glass cullet resulted in
improved mechanical properties in comparison with other synthesized samples,
whereas the values of compressive strength, impact strength and hardness were
51.65 MPa, 36.90 psi and 7.22 MPa, respectively.
