Clinker is the backbone of cement production which is a mix of limestone and minerals that have been heated in a kiln and have been transformed by this heat. PD CEN/TR 17365 is a standard that discusses a method for the determination of C3A in the clinker from cement analysis. PD CEN/TR 17365 describes the analytical procedures used to determine the content of C3A in the clinker starting from a chemical analysis on cement.
PD CEN/TR 17365 describes two methods, traditional wet and XRF analysis, which can be considered to be equivalent, in the scope of this CEN/TR 17365, for the determination of Al2O3, Fe2O3 and SO3. In PD CEN/TR 17365, the X-ray fluorescence (XRF) is the preferred method to be used for the determination of Al2O3, Fe2O3 and SO3.
PD CEN/TR 17365 on the determination of C3A in the clinker is useful for:
Tricalcium aluminate (C3A) is mostly related to the heat of hydration. It releases a large amount of heat during the first few days of hardening which generally results in early-age cracking.
PD CEN/TR 17365 provides you guidance for two methods, traditional wet and XRF analysis which helps you in the determination of C3A in clinker from cement analysis. XRF (X-ray fluorescence) analyzers are used to determine the chemistry of the sample by measuring the fluorescent X-ray emitted from a sample when it is excited by a primary X-ray source. Wet chemical analysis is used to decompose a sample with a reagent such as acids to dissolve in a solvent and identify and quantify the targeted elements using various measurement methods.
PD CEN/TR 17365 provides you with the principle in which the method is based on the calculation of the amounts of Al2O3 and Fe2O3 that occur in the clinker by the chemical analysis of cement corrected for the oxide fraction resulting from materials other than clinker.
PD CEN/TR 17365 exemplifies the required methods that help you achieve precision in terms of C3A in the clinker from the cement analysis so end customers get a superior quality product.
