| Abstract |
| Determination of pozzolana content in portland pozzolana cement
(PPC) by the hydrochloric acid extraction technique has been already
investigated. In the existing methods the varying degree of dissolution
of pozzolana contents causes its over- or underestimation. This could
be eliminated by using dilute hydrochloric acid (0.4 M) of known
volume. In the suggested method, errors due to the extraction of
ordinary portland cement (OPC) fraction and other constituents of
pozzolana were successfully minimized. These conditions can be
adopted to different types of pozzolana even in the absence of original
ingredients used in the PPC and estimation can be completed in 3-4
hrs by taking 4 samples at a time. The results obtained are reasonably
accurate (within ± 2.5% error). |
