    Procedures for rapid analysis of cement and cement raw materials were developed as modifications of existing methods. Silicon dioxide (SiO2), aluminum oxide (Al2O3), ferric oxide (Fe2O3), titanium dioxide (TiO2), phosphorus pentoxide (P2O5), and sulfur trioxide (SO3) were determined spectrophotometrically, and calcium oxide (CaO) and magnesium oxide (MgO) by titration with ethylenedi-aminetetraacetic acid (EDTA). All oxides except SO3 were determined using aliquots of a solution prepared by fusing the specimen with sodium hydroxide (NaOH) in a gold crucible. A separate specimen is required for SO3 analysis. The total time required for analysis of the five major oxides is between 1 and 1 1/4 hr per specimen. Six specimens can be analyzed simultaneously in 3 to 3 1/2 hr. In an additional 10 to 15 min each, SO3, TiO2, and P2O5 can be determined. Test results show the accuracies of the new methods are equal to, or better than those of the standard wet methods.
