Abstract:
Results are cited of long-time tests of 19 regular portland cements and 19 companion cments from the same mills which had been modified by raising the iron-alumina ratio from an average of 0.45 to 0.96, thus reducing the calculated compound tricalcium aluminate (C3A) from an average of 10.0 to 4.7 percent. The marked influence of changes in the percentage of C3A on the sulfate resistance of a portland cment is discussed.
