Analyzing the Mineral Composition of Concrete

The industry norm for the analysis of cement involves a fusion of the sample with a 41 mixture of lithium metaborate and lithium tetraborate. The fusion method involves accurately weithing 1.5 grams of sample and 7.5 grams of the flux into a Pt alloy crucible and fusion in a laboratory muffle furnace or a gas flame (commercially available for this purpose).
