| Abstract: | This study presents the effect of basalt as a flux and
mineralizer on the formation of Portland cement clinker fired at different
temperatures. Five mixtures are prepared by addition of different amounts of
basalt such as 0.0, 2.5, 5.0, 7.5 and 10.0 mass % to the kiln feed prepared for
the ordinary Portland cement clinker manufacture. Each mixture from the above
mixes is molded in one inch cylindrical bar under 300 kg/cm2 and
fired in muffle furnace at different firing temperatures such as 1200ºC, 1300ºC
and 1350ºC for 2 h as soaking time. The fired clinker is quenched in the air to
prevent the dissociation of the formed clinker. The degree of clinkerization is
studied by the determination of insoluble residue, free lime contents and the
identification of mineralogical phases such as C3S, -C2S,
C3A and C4AF by XRD analysis. The potential phase
composition of clinker is also calculated by the modified Bogue formulae. The
hydration characteristics are investigated by the determination of free lime,
combined water contents, total porosity, bulk density and compressive strength
for all clinkers fired at different temperatures. In addition, IR spectra of
hydrated cement pastes of some selected samples are studied. |
