“…The Bogue model is derived by defining the chemical composition of cement compounds as C 3 S for alite, C 2 S for belite, C 3 A for aluminate, and C 4 AF for ferrite [ 18 ]. However, Taylor [ 19 ] suggested that there are several micro-compounds in the cement compound, and Harrison [ 20 ] also presented similar results through 111 sample experiments. Since the amounts of cement compounds are very important to accurately determine the concrete properties, the accuracy of the Bogue models must be verified experimentally.…”

Calculation of Cement Composition Using a New Model Compared to the Bogue Model

The major cement composition ratios of alite, belite, aluminate, and ferrite have been calculated with the Bogue models until now. However, a recent comprehensive analysis based on various experimental data has revealed that the chemical composition of alite, belite, aluminate, and ferrite implemented by the Bogue models are slightly different than the experimental data, where small amounts of Al2O3 and Fe2O3 existing in alite and belite can change the prediction of cement composition. Since the amounts of cement compound are very important factors in determining the properties of concrete, improvement in the calculation would give more precise prediction for application usages such as climate change adaptable cement and high durable concrete manufacturing. For this purpose, 20 new models are proposed by modifying chemical compositions of the cement compounds and verified with the 50 experimental data sets. From the verification, the most accurate models are identified. The calculation using new models exhibit an accuracy improvement of approximately 5% compared to the Bogue models. Their applicable range is also presented. The study results are discussed in detail in the paper.

“…The 1960's through the 1970's saw a shift from classical analytical "wet" chemistry measurements (referred to as the reference and the alternate methods) to instrumental methods, including atomic absorption spectrometry, X-ray spectrometry, and a spectrophotometric/titrimetric scheme. Forrester et al [3], Midgley [4], Harrison et al [5], Aldridge et al [6,7], Stutzman and Lane [8], EN 196-2.2 [9], and a National Cooperative Highway Research Program report [10] have investigated uncertainty in chemical analyses of portland cements, with the latter three being based upon standardized methods. ASTM Subcommittee C 1.23, Chemical Analysis, amended the precision requirements with accuracy requirements in 1977 by replacing the third column in Figure 1 with a maximum difference between the mean of two replicate determinations and the value of a certified reference material.…”

Bulk oxide determinations from a pair of portland cements provide the basis for calculating the precision and accuracy values for X-ray fluorescence (XRF) analysis for both the fused glass bead and the pressed powder sample preparation methods. The measurements were collected through an interlaboratory study using two cements (Cement A and Cement B), and the two sample preparation methods were divided (roughly evenly) among the laboratories. Each of the approximately 45 participating laboratories provided six replicate measurements, analyzed in duplicate, for each of the two separate portland cements. Each laboratory reported an estimate for the mass fraction of eleven analytes:
